“He’s very protective of me,” bragged the owner of the German Shepherd I had been called out to evaluate. “He won’t let anyone near me.”
Indeed, her 18-month-old Shepherd was telling me in every line of his body that he did not want me anywhere near him. Head down, eyes wide and staring, muscles tense, and softly growling, he was not a dog I had any desire to approach. He was not, however, “guarding” his owner.
Many fearful or insecure dogs act just like this Shepherd, growling and posturing when people come near their special person. However, their body language tells the true story: these dogs are worried. Their weight is often shifted over their hindquarters, and they rarely position themselves in between the new person and their owner. They lack confidence, and make up for it with their “the best defense is a good offense” approach.
So why do they only show this behavior when they’re by their person? Simple: they’re only brave enough to show how they feel when they have “backup.” Social animals, whether dogs or people, tend to be more likely to act aggressively if they are part of a group whom they believe will back them up. We’re all a little braver with our buddies nearby.
Make no mistake, these dogs could still bite. However, allowing your dog to act in this way out of some misguided notion that he’s “protecting” you is both dangerous and unfair. It’s dangerous to other people, who could become victims of your dog’s insecurity if he ever feels pushed to defend himself. It’s unfair to your dog, who is stuck in a conflicted, adrenalized state any time he encounters someone new. It’s a bad situation all around.
The best ”protection” dogs are those who are well socialized, confident, and self-assured. A dog needs lots and lots of experience with people before he can pick out a truly threatening person from someone who’s merely a little different. To a dog who views everyone as a potential threat, your tipsy neighbor returning from the bar, your nephew with Cerebral Palsy, and the burglar who breaks into your home are all equally terrifying – and all just as likely to get bitten.
If your dog growls and barks at unfamiliar people, he’s telling you he needs your help. So how can you help him? Teach him that new people predict wonderful things. Teach him to look to you for help when he’s unsure how to react in a new situation. Show him a more optimistic worldview. Protect him from his fears just as fiercely as you wish him to protect you from true threats, because to him those fears are very truly threatening.
Do you have a truly protective dog, one who loves everybody, or an insecure dog? Please comment and tell us about your dog’s personality!

This article applies to my dog and I guess me as well since I am his owner. The second to last paragraph leaves me wondering… how do I teach him that new people predict wonderful things and how do I teach him to look to me for help when he is unsure?
We have come along way in teaching our Phoebe not to over react when new dogs or people approach us. Our main concern was that maybe she would no longer react to the bad or wrong. But I think some how they know who the bad guys are and so far she has never been wrong. Great article!
This was informative article, but it fell short of being truly educational to a pet owner by not offering ways to “teach him that new people predict wonderful things. Teach him to look to you for help when he’s unsure how to react in a new situation.” I read the article because this applies to my dog but I don’t know how to teach her not to do this.
I think it’s best to see a professional to work through these issues. But if you google BAT (behavior adjustment training) or counter-conditioning, you will get some ideas to teach your dog to be more comfortable. Another option is Control Unleashed.
The process for teaching dogs to accept scary people, or things, is called desensitization and counter-conditioning. These are the basics: http://www.aspca.org/Pet-care/virtual-pet-behaviorist/desensitization-and-counterconditioning but if your dog is truly aggressive, it helps to do them with the assistance of a trainer. You can find one via the listings at the Pet Professional Guild, Academy for Dog Trainers, or Karen Pryor Academy.
I agree-what a wonderful article. My dog is sometimes thought as “protective” because when she’s with me, she growls at the vet, etc, but by herself she is an angel with them. She also had a fear of new peopel and we worked with a reactive trainer to help her. But yes…protecting your dog is what helps a lot too! Always stick up for your dog. My dog also seems to act “protective” when someone hugs me by barking loudly and lunging, I have also worked with hugging people and dropping treats near her so she expects a good thing and doesn’t have to be afraid.
I keep a jar of treats on the porch so anyone who comes to the door can give her one.
My dog is a 14-month old Shepherd mix and is beginning to show what I think is “truly protective” behavior. He generally meets new people very well, with relaxed body language and a wiggly body, but has started putting himself between me and new dogs. He has recently even jumped in front of me and snarled at a dog that growled at us. So far, his behavior hasn’t been disruptive or concerning, but we are definitely going to continue practicing meeting strangers (especially men, as he only has regular contact with two) and being calm and polite around new dogs so that he doesn’t begin thinking that all new things will get me.
Oh, yes, I have a very anxious (clinically diagnosed) dog that exhibits this behavior. I had him in the back room at work and if I was in the room and someone approached the gate, he would charge it, barking and threatening. If I was not in the room, he would go lay down under the table and just quietly watch the person. He is on medication which helps him quite a lot with his overall anxiety but no amount of desensitation & counter-conditioning has convinced him strange humans are not scary.

This is my dog all over although it’s other dogs he’s “protecting” me from. He’s a herding dog…who was attacked as a puppy. I’ve always felt he would get hysterical in compromising situations… Although we have an older dog and cats…any “strange” animal is cause for a strange dichotomy. I MUST protect…but I’m AFRAID…but I must be BRAVE…but its SCARY. Poor baby gets worked up into such a tizzy he doesn’t hear anything any of us say that might help him. We work all the time…but its so sad because he wants to go places and see things and meet the new animals…but…
I’m in the same boat! But I have a 145 lb. Great Dane so it can get really scary. Mostly with other dogs.
I have a dog like the one in the article. I can’t have people over, I walk him with a muzzle. He acts out the most when with my daughter.
