Physical exercise is necessary and healthy for all dogs. However, there are a few common problems we see in client’s dogs who are not exercised properly. Today we’ll discuss one of the biggest problems, overarousal due to exercise, and the myth that you should exercise “crazy” dogs more.
Arousal refers to a dog’s level of excitement and emotional control. A highly aroused dog will be very excited, with a fast heartrate and respiration and poor impulse control. He may have dilated pupils or chatter his teeth. He may pant, jump around or on you, or vocalize incessantly. He may become grabby or mouthy. Alternatively, he may become “locked on” to an activity, freezing in place and staring intently at the object of his obsession, spinning in circles, or pacing.
Highly aroused dogs are stressed. Remember that stress is not necessarily bad. When we think of stress, we often think of negative stress, or distress. However, there’s also positive stress, known as eustress. Winning the lottery and having your home foreclosed on are both stressful activities, and your body actually responds to them the same way even though your emotional response to each is different. This point is important for us to understand as it relates to our dogs, because happily exciting events still create a physiological stress response in your dog’s body.
Why does this matter? Stress causes physical changes in the body. When you or your dog become stressed, your body releases certain stress hormones into the bloodstream. These stress hormones don’t just instantly dissipate. They hang around for awhile (the most commonly quoted length of time is 72 hours, but estimates range from mere hours to an entire week depending on who you ask).
Consider this, then. If you engage in activities that cause your dog to become aroused, and therefore stressed, every day, your dog will always have high levels of stress hormones in his bloodstream. High arousal becomes the new norm. Consider how you would feel if you won the lottery, rode a rollercoaster, or attended your favorite band’s rock concerts every single day. Our bodies aren’t built for prolonged periods of excitement, even when the excitement is positive.
What does this have to do with our dogs? I’m often called in to work with dogs who have trouble controlling themselves or calming down. These dogs are often reactive and hypervigilant. These dogs are also often victims of the wrong sort of exercise. Exercise that amps your dog up is okay in moderation, but allowing your dog to engage in it every day will likely do more harm than good. This is highly individual, but is most commonly seen with ball- or frisbee-obsessed dogs playing fetch every day or highly dog-social and excitable dogs visiting the dog park or daycare regularly.
If this sounds like your dog, there is hope! Cut down on overly arousing activities and replace them with other physical and mental exercise. Save these exciting activities for special times. My dogs both enjoy the flirt pole, but only play with it a few times a month due to how highly aroused they get while chasing it. Layla adores lure coursing above all other activities, but she takes 3 full days to recover after just a few runs after the lure because she becomes so over-the-top waiting for her turn (words cannot describe the bark-scream-screech sound she makes in line). Dobby loves to play fetch, but two days in a row with the chuck-it or frisbee creates a dog who’s not very pleasant to live with.
In future posts, we’ll discuss other common exercise pitfalls as well as some great ways to exercise your dog. Have you ever had to limit an activity your dog adored because it caused him to become too overstimulated? Please share your stories in the comments below!

Interesting. My dogs play fetch every day, but don’t get over-aroused. They get hard to live with if we DON’T play fetch! It’s a good thing this works for us. We have basically zero other physical exercise options, since neither dog can really be out in public and we live in the city.
Layla is super excited with lure coursing. The hardest part is holding her back till she is suppose to start.
Thank you! I’m a dog trainer and one of my number one pieces of advice to clients is to give their dogs more MENTAL exercise. Excellent article.

Interesting post. My dog can get extremely stressed if she has to watch other dogs play and can’t participate. Gets very aggressive, barking and lunging. I would like to help her learn self calming techniques and have been working with a clicker while she plays with her favorite ball which also causes her to become highly aroused with some positive results. I would welcome any suggestions from readers
So maybe leaving my improving papillon with his former pack for a day or so a week is a bad thing? Doh! I’ll have to find a way to calm him down…
Wish I had read this when I adopted my guy (who looks like the dog in the picture). I took him to daycare frequently because he was so hyper and they would remark that he would play straight for the 7 hours he was there, and he was only 5 months old when he started attending. I walked him 3 hours a day when he didn’t go to daycare because he drove me nuts if I didn’t. Then he got kicked out of daycare for being too reactive. I wasn’t sure if it was possible to make him tired. It is going on 5 years now and I still have to be careful to regulate his activities; he is an adrenaline junky.
Great article. Looking forward to the follow-ups. I have 2 GSDs that we take to the dog park every day and they do great at the park. Getting into the park, however, is a different story. Actually, going for rides anywhere is the different story. The over-excitement, bouncing and bark/screaming can get crazy but quickly subsides as soon as we enter the park.
Great post. I’d say one key is to find ways to combine physical and mental exercise. Or to put it slightly differently, to make sure the dog’s task is at an appropriate level of cognitive as well as physical challenge – not too easy, not too hard (both lead to frustration and over-arousal). Examples might include tracking or searching for toys over somewhat rough terrain, some types of frisbee workouts, physically challenging trick training/”canine parkour”, retrieve work (land or water) which incorporates steadiness, marking and directionals, *appropriate* play with suitable dogs, and of course (good) agility/obedience/schutzhund etc. training.

Interesting article! My dog use to get super over excited from playing fetch or chewing on raw hides. She didn’t know when to stop or how to stop. I like how you describe the situations.

I just read this post and enjoyed it very much. I have an over-the-top rat terrier who goes over the 6 ft. privacy fence in my backyard. She has accompanied me on runs up to 14 miles…loves, loves, loves to run. Like Layla, Zoey gets more worked up in anticipation of the run than actually running. We take frequent water breaks, so it is interesting to observe her actually calm down on the run and take less water than she does after our first break where she is recovering from her anticipation excitement.
I also have a permanent foster in the form of a senior JRT who goes nutso if given the opportunity to play with her basketball. She rolls it around the backyard until it gets stuck. Then she barks until she or I can shift it. I do not let her play with the basketball very often, just special times. She’s less intense with a tennis ball. I keep the balls put away and she lies around and sleeps.
Am eager to read your subsequent posts on this topic.
I have a very active border collie x kelpie who I used to exercise profusely – he would get 10 minutes of agility training, an 8km walk and then free running in the paddock for an hour every day. And he would never stop. So I would increase the exercise even more thinking I had to tire him out somehow. Then I worked it out! The free running was just working him up higher and higher and higher and it seemed like he could never get enough, then he would come inside and cause fights with all the other dogs! He was completely unable to come down emotionally and mentally. He now gets agility training for about 5 minutes 3-5 times a week, and a 5km walk on lead every day. He still gets let loose in the paddock as he loves to stretch out his legs and run, but only for short stints a couple of times a week. The steady walk at a fast pace is great for him as it exercises his body but calms his mind as opposed to running free where there is nothing calm happening. Today we went to the beach and I allowed him to run free – after about 20 minutes he came back and trotted beside me for the rest of the walk. Much happier dog :)
Couldnt agree more. I am currently working with 2 v energetic and easily overexcited large shelter dogs. One thing I like to do is taken one to the park (at a quiet time) and break up periods of arousal – sniffing, meeting other dogs, playing with toys etc. with quiet time just sitting under a shady tree, doing some simple training exercises or just watching the world go by and rewarding calm behaviour – i find those quiet times invaluable for the dogs, for me and for future owners.
Something along the same lines; my shar-pei/lab mix loves to play with other dogs at the park but sometimes she will click into an over-excited mode and begin to growl. I can see her eyes widen and something about her body language, as well as the noise she makes, tells me she is too hyped up. When this happens, I intervene, giving her the “go down” command which means she must lay down on her side. I go sit with her and make her lay completely on her side (including head down) for about 5-10 seconds (unless other dogs are bugging us, in which case I move her to another part of the park and just let her sit for the next phase), then I let her up with the “okay” command, praise her and bring her back to the bench and have her stay with me until she calms down. She will be panting and have wide open eyes and her movements will be very quick, such that, even though she is sitting with me, she will be intent on rejoining the fray or just watching everything else going on at the park. Anything but focus on me. So I just keep her with me until the breathing slows down and she can stop being so antsy. Since this usually happens after we have been at the park for a while, it is often the signal for me to head home. This is a system I developed after both observing her and paying close attention to dog training methods. Each dog I’ve had needed something different.
Reading your column, I realise that I might have done better to always just leave the park when she got wound up like that, and I think I will do so from now on. It was very insightful and helpful. I don’t know if I’m doing the right thing or not by making her go into the down position, but she responds immediately to this command despite being wound up, whereas she won’t respond to my calling her name. For me, the “go down” command has been useful especially because, when there are several dogs growling and that only-too-common scene at the dog park where all the dog owners start moving toward the dog pile, I can get my dog out of there quickly without having to put a hand anywhere near dog jaws. Usually the roughhousing cools off quickly but there have been a few times when I have been glad to get my dog out before the full-on fighting started.
I think that most, if not all, of these situations are multi-dog responses. What do you think? What I mean is, when I see my dog beginning to display the signs of stress, as I mentioned above, it is usually when she is playing in a group and it is hard to say which dog is tipping the scale from play to fight. My feeling is that the pack is feeding off of each other, so to speak, and there is no single dog causing it. However, the human behaviour at the park has always been to place blame. My dog doesn’t get blamed because I get her out in time and she responds so well to my commands that, as far as I can tell, no one thinks she was the cause, but I do feel she had as much responsibility for the aroused situation as any other dog. They were all in there getting to that point together. Big dogs, little dogs, they all were taking part. I’m not saying they should know better than to let it escalate; that’s our job; but I’m saying that no single dog is to blame and it bothers me when I see the person with the biggest, most aggressive type of dog getting the glares and sometimes being yelled at, while the little dog was probably going at it just as much. It’s our human nature to protect the little ones but I just would like to see less blame/guilt laid on the big dog owners. What do you think of this? What do you know of this kind of dog-dynamics? How aware are dogs of size, especially in a pack frenzy? Why don’t the little dogs run for their lives in these situations? Do they think they are big?
Well, thanks for the great articles, they are really eye-opening, down-to-earth and helpful. If you think I should try something different with my dog, I’m very open to hearing about it. She is about six and I got her at about eight months. I also have another dog, a 13 year old chow mix. (and three cats, three chinchillas and a hamster…yoiks)
One thing I will do, and actually have been doing just by chance over the last couple of years due to my schedule, is take a mellower walk for a few days after my dog has any of these wound-up play sessions. I like to vary our outings, so the dog park is not the only place we go for recreation. I live in Berkeley, California, so we can hit the beach, the trails, even the snow in the mountains if the desire takes us. I also like to just explore the neighbourhoods. Or sometimes we will go to the City (SF) and do some lead walking in the crowds. Whatever strikes our fancy.
I’m glad I found your site and am going to share it. You’ll be rich and famous, mark my words…
Rebekkah, you might enjoy watching Nicole Wilde’s new DVD Too Much of a Good Thing http://www.dogwise.com/ItemDetails.cfm?ID=DTB1289 Much of that footage is filmed a dog park. She recommends taping your dog’s interactions and slowing the film down and observing the many signals that dogs give each other. There are some dogs who are plain rude and lack the doggie social skills of others. Then there are handlers who are slow to respond to their dog’s behavior and allow the dog to get over threshold. I see that happening more than any size bias or finger-pointng at large dog owners. But that said, don’t most good dog parks have separate sections for large and small dogs to play and don’t let them run together?
