Dog-Dog Aggression Between Housemates Part Four: Training

Last week I discussed the management techniques I used to keep Trout and Layla safe and separate after their recent fight and resulting injuries. I cannot emphasize how very important management was in our success – without it, I doubt we would have ever been able to get the two girls back together. That said, there was still some work to be done. Today, I’ll cover the training and behavior modification exercises that we employed to reintroduce the two dogs to one another.


Starting right away, we began to do short sessions with the dogs on opposite sides of their gates or ex-pens. We would take the blankets off the gates so that the dogs could see one another, walk them within sight of each other, then feed them lots of treats. After 10-20 seconds of treating, we would walk one of the dogs out of sight and immediately quit feeding both dogs. The premise was simple – good stuff only happened when the other dog was present.

When we first started these exercises, the dogs were noticeably worried. Trout frequently stared at Layla and sometimes growled, her posture stiff and upright. Layla avoided confrontations, looking away and licking her lips, clearly frightened. This behavior on Layla’s part was quite surprising to me. In the past, she’s always been eager to engage if another dog started something, but I suspect that with her increasing age (she’s nine years old) and injured leg she just wasn’t feeling up to another confrontation. When Trout growled or postured, her handler instantly stopped treating or paying attention to her and walked her away, while Layla’s handler praised and treated her for avoiding conflict while also moving her further away. We never allowed growling or posturing to continue for more than a second before intervening. Remember, practice makes perfect – and we certainly didn’t want Trout to get better at these behaviors!

Within a couple days, these positive conditioning sessions began to show real results. Trout’s posturing became less intense and Layla’s appeasement signals likewise lessened. Both dogs began to visibly brighten when they spied their housemate on the other side of the gate or ex-pen, looking for their treats. They also began to signal in friendly ways towards one another, sniffing from a distance and returning calming signals. We praised them enthusiastically for any pro-social behaviors, and Trout especially seemed to really need this extra reassurance that she was doing well.

As she became less insecure around Layla, Trout’s posturing and growling melted away. This is an important point. Frequently, owners think that their dogs are growling because they’re pushy, mean, or status-seeking. However, much like Trout, these behaviors are often an indicator of a problem with insecurity. Imagine, then, the damage that can be done by punishing a dog for growling or otherwise displaying their discomfort. Not only would punishment have potentially suppressed growling and other very useful indicators of Trout’s comfort level, but it also would have completely reinforced her belief that she was correct to worry when Layla was around. By pairing Layla’s presence with good things (treats! praise! neck rubs!) and viewing any growling as information that the dogs were too close, we were able to quickly change Trout’s reaction to Layla for the better.

Oops! Sometimes we made mistakes. Here, Trout got way too close to Layla, and began to display whale eye and other signs of tension. We immediately put more distance between the two dogs, and Trout once again relaxed.

Oops! Sometimes we made mistakes. Here, Trout got way too close to Layla, and began to display whale eye and close her mouth – both major warning signs. We immediately put more distance between the two dogs, and Trout once again relaxed.

At this point, we began taking short walks multiple times a day – just halfway to the corner at first, then all the way to the corner. We started by walking the dogs across the street from one another, moving them in the same direction but allowing for plenty of parallel distance between them. Both dogs were given treats for looking at the other dog in a soft manner, as well as receiving frequent rewards for walking nicely. If either dog began to look tense or nervous, we immediately veered further away from one another, giving them even greater distance. When they were both soft and relaxed, we moved slightly closer, lessening the distance between the two.

Within a week, the two dogs were able to walk side-by-side in a relaxed manner. They began sniffing each other as they walked, and following one another to especially enticing smells. They started to urine mark over special smells together. While they were still kept completely separate inside, their outdoor walks allowed them to start interacting as a team once again.

Inside, we continued to experience problems with guarding. Both dogs guard resources (food, toys, special resting places), so we had to be very aware of potential triggers. If either dog growled or stared at the other, the offender was immediately but calmly escorted to a crate or room for some alone time, while the dog who had been growled at was rewarded liberally with treats and praise for not responding. In just a few days, Layla began to run to the treat cupboard and wait for a reward during the rare moments when Trout happened to growl, and both dogs began to posture and threaten the other less frequently.

To begin working on reintegrating the dogs indoors, I returned to one of my favorite tools for behavior modification – the Protocol for Relaxation. This step-by-step protocol teaches dogs to relax while stuff happens around them, and both Layla and Trout were already quite familiar with it. I started running through the protocol once or twice a day, at first with the dogs lying on mats on opposite sides of a baby gate, and later with them side-by-side but with Trout tethered. After a week of successful protocol repetitions, when both dogs were looking soft and relaxed on their mats, I untethered Trout. Outside of training sessions the dogs continued to be kept separate, but while we were actively working on the protocol they were able to be loose together, relaxed on their individual mats.

These three main exercises – positive associations on opposite sides of the gate, parallel walks, and the Protocol for Relaxation – set the stage for a successful reintroduction. Within a week, we began allowing the dogs to pass by one another off-leash without interacting when switching them into different areas of the house, and later began to allow short (2-5 minute) periods of time when they were loose together but heavily supervised. We continued to keep them apart for the majority of the time, but built up the amount of time they could be around one another gradually.

Relaxing during the Protocol for Relaxation, off-leash together!

Reintroduction after a serious fight is a slow process, but it was worthwhile in the end. After a month of gradual reintroductions, we were able to take the ex-pens and baby gates down completely. The dogs continue to be separated if left unsupervised (something we’d done prior to this incident as a matter of course), but are otherwise peacefully coexisting once again. Three weeks into this process, the two began playing together once again, at first with frequent breaks and exaggerated body language, and then with more relaxed signals as they once again became comfortable with one another. Today their interactions have returned to the pre-fight levels of peace and playfulness.

While I’ve coached many, many clients on reintroductions such as this, I’ve never before experienced inter-dog issues with my own pets at such a serious level. I can empathize with the stress and anxiety of dealing with dogs who don’t get along. My mantra for clients in similar situations has always been that “slow is fast,” and Layla and Trout were proof that this is indeed the case. Anytime we tried to rush through exercises or pushed the dogs, things fell apart. Allowing both girls time to heal, physically and emotionally, and setting them up for success with one another, gave them the tools to progress at their own paces and eventually to rebuild their relationship. We’ll continue to be vigilant in avoiding situations that could trigger a repeat of their fight, however I feel confident in saying that the dogs are better equipped to avoid conflict in the future due to the hard work we put into helping them succeed during this time.

If you’ve ever experienced inter-dog aggression in your own household, I hope your experiences at reintroduction were every bit as successful as ours. Remember, slow is fast, and it’s important to work at your dogs’ own paces. Feel free to share your tips, tricks, and stories in the comments section below.


Dog-Dog Aggression Between Housemates Part One: the Fight

In retrospect, we should have seen the attack coming. On two separate occasions after full days of running around, our normally sweet and friendly dog Trout had snarked at different foster puppies over food. Both times she stopped quickly without making contact when we intervened, and was then confined to a room to rest. However, both times she also showed a concerning lack of the typical warning signs dogs give off before lunging or snapping, only freezing slightly for an instant before she went after the puppies.

Waiting for treatment at the e-vet

We chalked Trout’s concerning behavior up to soreness and not feeling well. With a mystery illness resembling Addison’s disease, her body struggles to handle stress, including the good stress of exciting events. Her muscles have wasted with the disease progression, and her energy level fluctuates. She has episodes of GI distress where her reflux is so bad that she will attempt to eat anything she can get in her mouth – cloth, cotton batting from dog toys, and even foam from dog beds. She has full-body muscle spasms, twitching and groaning as she lies on the floor. Her cognitive abilities have suffered too, and while on some days she’s the sweet, happy dog we’ve always loved, other days she seems confused by even the most simple routines or cues. We keep her comfortable on a regimen of medications, and she continues to have more good days than bad.

On the day of the attack, Trout was not having a good day. She had run hard for close to an hour at the park the day before, a special treat that we typically wouldn’t let her indulge in. However, it was one of the first nice days of spring, and she’d been doing well for a few weeks. She was extra sore this day, and I could tell that she was having some cognitive issues as we did a short training session. I kept the exercises easy, and at the end of the one-minute session she was able to end on a happy, successful note. I then called our other dog, Layla, into the room where I was working – something I’ve been doing for three years, since I always work one dog and then the other.

Today, that was a problem for Trout. As Layla entered the room, Trout stiffened up and growled, guarding me and the treats. I grabbed for her, missing as she launched across my body and bit my elbow, then attacked Layla. If you’ve never seen your beloved pets fight, the sight is chilling. Layla instantly defended herself, and my boyfriend and I each grabbed a dog. We had to wait for the dogs to let go of one another, as both were holding on in ferocious terrier grips, and pulling them apart would have caused more damage. The fight was over within 20 seconds, although in the heat of the moment it felt like much longer longer.

Unfortunately, that twenty seconds was all it took for both dogs to sustain injuries. We packed them up in the car for a trip to the e-vet as I contemplated the seriousness of Trout’s attack and tried to hold back tears over the sight of Layla’s deep wound.

Over the next two weeks, I’ll be writing about our experiences with Trout and Layla. What did the location of their bites have to say about their intentions during the fight? How did we manage the two dogs to prevent future incidents? How did we re-integrate them into the same household? I’ll cover all of these questions as I discuss living safely with dogs who’ve hurt one another.

In retrospect, we should have seen the attack coming. However, love is blind, and while I likely would have picked up on the warning signs with a client’s dog, knowing and living with my own dogs skewed my perspective. There’s a reason that even professional dog trainers hire other professionals when our dogs have issues, and this story is a good reminder of that. I’m grateful that Matt and I were right there when our dogs went at it. This story could have been very different had we not been – one of the biggest reasons why I never leave the two dogs unattended together.

Have your dogs ever fought with their housemates? How did you handle the situation? Please share your stories in the comments below, and watch for the next installment in Trout and Layla’s story next week as I discuss what the location of the bite wounds told me about the two dogs’ intentions.

Overzealous Greetings (and Other Tales of Toddlers and Puppies)

The other day as I was grocery shopping, a toddler ran up to me and hugged me. I smiled and put an arm on his shoulder as his mother rushed up. “I’m so sorry!” She exclaimed. “He really loves to meet people.” I assured her that it was not a problem and spoke briefly with the outgoing little boy before heading on my way.

Later that same day, my foster puppy was accompanying me on a shopping trip at the local pet supply store. As we were ambling along the treat aisle, a large Husky came around the corner of the aisle on a flexi leash. My foster pup jumped on his head, and the Husky stood still with a soft, relaxed body while the squirmy pup wriggled around him in joy. I apologized to the dog’s owner as I calmed and corralled the excited puppy. “No worries!” she exclaimed. “Thor wouldn’t tolerate that behavior from an adult dog, but he really likes puppies.” We chatted for a few moments longer, and the dogs politely sniffed noses as we walked away, my foster much calmer and more polite after a few clicks and treats for appropriate behavior around his new friend.

Dogs aren’t all that different from us, if you think about it. I thought the excited greeting from a toddler was adorable. If an adult tried the same thing though, I wouldn’t react so kindly. In fact, if a strange man ran up and grabbed me in a bear hug, I’d likely respond quite violently in defense even though I’m not typically a confrontational or violent person.

Dogs also react differently to puppies, adolescents, and adult dogs. Most dogs are quite tolerant of rude and clumsy greetings from puppies. They understand that the puppies are still learning and aren’t all that polished. Just as we understand that toddlers are still learning social behavior, well socialized adult dogs generally forgive social blunders in pups.

The problem develops when puppies never learn appropriate social skills. Adult dogs who greet inappropriately (by rushing and jumping on other dogs, for example) become the canine equivalents of a forty year old man racing up to grope my breasts. It’s just not okay, and other dogs are likely to react aggressively even if they’re generally quite friendly and easygoing with other dogs.

A large part of the blame for such boorish social behavior in dogs lies at their owner’s feet. Just as responsible parents teach their children appropriate social behavior (for example, the toddler’s mother apologized for his rushing up at the grocery store and helped him to practice greeting me more appropriately by instructing him to wave and say “hi”), responsible dog owners can teach their charges to be polite around other dogs. Socializing your dog appropriately helps him grow into a model citizen of canine society.

So, how do I guide my foster dogs through appropriate interactions? First of all, I focus on teaching them to greet other dogs calmly. If puppies squeal and lunge in excitement every time they see a new dog, they grow into adult dogs who rush up to other dogs or react explosively on leash at the sight of each new dog. This isn’t a healthy social reaction, and preventing this behavior from developing is much easier and faster than fixing it once it’s become a habit. The solution is simple: I only let calm puppies greet other dogs. If my puppy is excited about the other dog, we move further away and do a few simple obedience behaviors until the puppy’s calmed down, at which point he’s rewarded for his calm behavior by earning permission to say “hi.” If my puppy absolutely can’t calm down, we may switch to the Watch the World game for a few minutes to get him in a better mindset. Just as parents of excitable toddlers may hold onto their children’s hands and instruct them on waving instead of hugging, gently guiding your puppy in social niceties will help him learn the best way to behave. Furthermore, since most puppies really enjoy meeting other dogs, they learn quickly that civilized behavior is the fastest path to gain access to their new friends.

In addition to teaching my puppy polite greetings, I also provide him with lots of opportunities to play and interact off leash with a variety of other dogs. Just as a parent will allow their child to converse with a variety of other kids, teenagers, and adults, letting my puppy socialize with others of his species keeps the doggy language skills he learned with his littermates sharp while also polishing away any rough bits. The bigger the variety of ages and sizes of dogs that I can safely introduce my puppy to during this time, the better. Ideally, I like to arrange 3-4 play dates a week for my puppy with known dogs. We avoid dog parks and other situations with dogs of unknown health and behavioral status for obvious reasons. Just as I wouldn’t bring a toddler to a frat party, I know my puppy’s not developmentally ready for the crowd of adolescents at most dog parks. And of course, I want to wait until my puppy’s vaccines are on board before going around other dogs who may be carrying potentially fatal diseases such as parvo or distemper, just as many parents are now avoiding crowded attractions like Disneyland until their children’s vaccines are current.

If you’re raising a puppy, remember that socializing him is more than just introducing him to others and waiting for him to figure things out on his own. Just as you would school a toddler on appropriate interactions with new people, it’s important to provide your puppy with lots of feedback on how to best get along in our world. Well-socialized adults of all species understand how to communicate with one another, including respecting one another’s space and using culturally-appropriate greetings.

Diary of a Fearful Puppy: Weeks Two and Three

Last week, we covered formerly feral puppy Chowder’s first week in our home. By the end of the first week, Chowder was snuggling with us in the evening and enjoying regular play sessions with our dog Trout. He would still run away when approached and flinch if we reached towards him. His crate was his safe haven, and he ran to it whenever he needed a bit of space – a behavior that made it easy to move him from one location to another without having to handle him, as we could carry the crate with Chowder inside wherever we needed him to go. Chowder would still freeze if handled or held, but he was beginning to cautiously investigate his world.


When Chowder first arrived at our home, we’d noticed some odd hairless spots on his legs and feet, and over the next few days these lesions began to crack and bleed. Soon new spots appeared, and a trip to the vet was in order. When I arrived at the vet clinic, the tech attempted to take Chowder into the back room. I firmly but politely refused, and instead stayed present for the entire skin scraping procedure, feeding Chowder bits of hot dog and cheese. He wasn’t able to eat while being restrained as he was too scared, but quickly returned to munching on bits of treat after the procedure was finished. We played some sniffing games where I scattered treats on his bedding for him to find, and these increased his comfort level and confidence noticeably.

This vet visit brought up an important point about fearful dogs. You are your dog’s advocate. It’s always okay to stand up for what’s best for your individual dog. I knew that had the vet tech taken Chowder to the back room, she would have reached into his crate to pull him out (gently, because she was a kind person who loved animals, but still in a way that would frighten Chowder). While he would comply with this, it would break the compact we’d formed with him where his crate was his safe, private place and no one would ever remove him from it. Since Chowder wasn’t likely to come out of his crate on his own and we needed to handle him, we instead took his plastic crate apart and removed the top half of the crate. While still stressful, this allowed Chowder to remain safely planted on his dog bed with four walls around him, and minimized the amount of handling he had to endure.

Chowder’s skin scraping was negative, so he returned to the vet clinic a few days later for a second visit so that he could be seen by a veterinarian. This time he remembered the sniffing games he had played before and cautiously came out of his crate on his own to search for treats which I scattered all over the floor. We repeated the skin scraping, which was again negative, and also ruled out most strains of ringworm by looking at his skin under a woods lamp. Since he wasn’t itchy but his lesions were getting worse, the vet decided to start him on an antibiotic to see whether the spots might be caused by a bacterial infection. Luckily, this turned out to be the case, and the swollen spots on Chowder’s legs and feet stopped bleeding and became less inflamed. By the time the course of antibiotics was over, Chowder was growing new fur over the spots and looked much better!

During the next couple weeks, Chowder continued to accompany me to training classes three times a week, where helpful students tossed him treats. My nose work students were especially kind, and a different student stayed after their own dog’s class each week to take Chowder through the last of the three nose work classes I taught on Friday evenings. Nose work is one of the best confidence builders for shy and fearful dogs. On the first week of his class, Chowder was reluctant to move more than a couple steps away from his safe spot near his crate and was too worried to put his head into a cardboard box in order to eat treats. We placed the boxes near his safe spot and put food on the outside of them, and Chowder sniffed his way over to eat the chunks of chicken and hot dog. By the second week, he was able to eat treats out of shallow boxes, and we started to see him perk up as soon as the boxes were in sight.

I noticed that, while Chowder was making strides in bravery, he continued to have a very difficult time recovering after something startled him. This was a problem, because at this point in his limited experience with people, everything startled him. If someone reached towards him too quickly or a noise spooked him, Chowder often hid and remained jumpy for hours. He would stop taking treats and shut down.

I consulted with a veterinarian friend of mine, and she agreed that the potential risks of using anxiety medication for Chowder were much lower than the risks to his developing brain and body from such constant stress. She recommended that we try a very small dosage of a common anxiety medication, alprazolam, which I already had on hand for one of my own dogs and which has been safely used in human children.

The results were beyond our wildest dreams. While the drug didn’t make Chowder brave, it did help him recover quickly (within 2-5 minutes, instead of hours) from startling events. After making sure he reacted well to it at home in a quiet environment, we used two doses of the drug: once while he was in an ex-pen during a training class and once when I brought him to a friend’s home for game night. After just these two doses, I noticed that Chowder’s ability to recover from stressors even without the medication was greatly improved. Because he’d had success in these situations, he had learned that he could handle them. We discontinued the medication, and he has continued to make lovely progress without it. While my veterinarian friend was quick to point out that these results aren’t typical, she also theorized that perhaps because the medication was used so early in Chowder’s behavioral modification and before he’d had many scary experiences, it was much more successful than it may have been had we waited months or even years to try it, as many people do. Just as doctors often recommend taking pain meds at the first sign of discomfort after surgery in order to keep on top of the pain, getting on top of Chowder’s anxiety and offering him help right away made a big difference in preventing his fear and anxiety from spiraling.

Along with all of these successes out in the world, Chowder also had a very exciting thing happen at home: he finally got to meet Layla. Because Layla is dog aggressive, we waited for two weeks before the two dogs met without a baby gate between them. The meeting went well, and the two dogs were able to hang out in close proximity without fireworks. We didn’t yet allow them to interact beyond casual sniffs as they passed by each other and made sure that there weren’t any valuable resources (such as knuckle bones) that Layla might guard. Chowder’s body language with Layla was beautiful – respectful and friendly without being fearful. On the few occasions when Layla felt uncomfortable and snarked at him, Chowder responded appropriately by backing off but was not frightened. His dog skills really were suburb for a tiny puppy!

At the end of his third week with us, Chowder had developed the ability to calm down and recover quickly if something scared him. He continued to learn new things (“high five” was his favorite trick!) and explore his environment. He had also made several dog friends and eaten treats from over fifty people. He was learning that we would respect his choices and that he could investigate his world when he was ready to do so. Even more importantly, Chowder was learning that he had the power to influence the behavior of those around him. If he moved away, people would back off and give him space. If he sat, people would hand him treats. His confidence was growing every bit as fast as his body (which doubled in size in the space of three weeks, from seven to fifteen pounds).

Have you ever brought home a fearful puppy? What did you do to socialize your new charge and build his or her confidence? What would you do differently if you could do it all over again? Please comment with your tips, tricks, and stories!

Diary of a Fearful Puppy: Week One

Last week, I covered fearful puppy Chowder’s first three days in our home. After three days, Chowder was reliably taking food from our hands, enjoying regular play sessions with our dog Trout, and beginning to play with us.

Chowder’s overall ability to cope with life in our home took a great turn for the better after the first 72 hours. He continued to be a champ at using his potty pads and settling in his crate, and we were able to use his crate to move him from one area to another. He would run into his crate as we approached, and we could then shut the crate door and move the crate wherever we needed him.


Because of this, we were able to expand his world from our kitchen and bedroom to include my office downstairs. Our house has a relatively open floor plan, so we used an ex-pen to gate off the downstairs living room (which has white carpet) and a baby gate to close off access to the steps. Chowder could then run around my office and the adjoining room, which were both set up with water, toys, and potty pads.

Once Chowder could hang out with me while I worked, I began doing hourly training sessions with him. The clicker was an important tool in shaping his brave behaviors. Each hour, I would spend sixty seconds clicking and treating for brave behaviors. Whenever he took a step towards me, I clicked and tossed a treat away. This provided him with double rewards: not only did he get a treat, but he also got to move further away from me, which made him feel more comfortable. I wanted to be sure not to put too much social pressure on him, and this game allowed him to approach to a distance that felt comfortable without the conflict of moving into my space to eat.

Over the next week, Chowder learned the hand target game and quickly came to enjoy following my hand all over to earn clicks and treats. On his fourth evening with us, we discovered that he really liked popcorn. He began offering sits, which I clicked and rewarded with a small piece of popcorn. Within a couple minutes, he was offering to sit on a verbal cue with confidence.

One interesting behavior pattern that we noticed with Chowder was his differing level of confidence throughout the day. He was consistently timid and fearful in the mornings, and grew in confidence as the day progressed. By evening, he was much more likely to approach us and allow us to touch him, but would then regress overnight. We took advantage of his bravery in the evening by letting him snuggle in bed with us each night before he went into his crate to sleep. We set his crate up on the bed with the door open, and let him choose to come to us. Popcorn and cuddles became nightly themes, and by the fifth night in our house he actually fell asleep on our bed in between us.

We began having Chowder wear a body harness, which we put on each morning with lots of patience and food. Handling was still difficult and putting the harness on frightened Chowder, but he recovered quickly and we felt that the benefits of the harness outweighed the potential damage done to our relationship in putting it on. Had Chowder been too scared to eat while having the harness put on, we wouldn’t have done this. We attached a dragline to this harness and began allowing Chowder to spend short periods of time loose in the house when we knew he was empty (having just used a potty pad). Layla was confined when Chowder was loose, since the two dogs were still not ready to be loose together. Chowder loved these periods of freedom to run around with Trout and cautiously explore the house.

During this first week, I began bringing Chowder to the classes I was teaching. I set him up in an ex-pen in a corner with access to his crate and potty pads. A sign on the ex-pen told students, “Hi! My name is Chowder and I’m shy. Please don’t try to pet me, but you can feed me treats. Thanks for helping!” My students were wonderful at tossing treats into Chowder’s area when they were nearby, and he would cautiously come out of his crate after they moved away to eat. He watched the other dogs in class avidly, wagging his tail whenever he saw a new dog.

By the end of his first week with us, Chowder had made some remarkable progress from the near-feral puppy we initially brought home. He’d fallen asleep in bed, was accepting gentle petting in the evenings, and knew a couple trained behaviors which he could use to interact with people in positive ways. He was still quite timid and would run away if approached or if we reached for him, but he was on his way!

Next week, I’ll talk about Chowder’s second and third weeks in our home. In the meantime, I’d love to hear from you. Have you ever brought a fearful animal home? How did you go about socializing him or her?
