Guarding is an instinctual behavior for dogs. It is useful to us when they warn strangers who intrude on their (and our) territory. One of the earliest benefits dog provided to man was to serve as an early warning intruder alert system.

Territoriality is, simply stated, guarding space. It is the dog’s way of saying “this space has value and it belongs to me and my pack.” In fact, dogs guard all sorts of things, some tangible, such as food, others intangible such as space.

When they guard these items from outsiders it can be helpful. I leave my home knowing my dog will be alert to an inappropriate intrusion. Dogs also guard tangibles and intangibles from one another. You shouldn’t expect to see a submissive dog take a bone or scrap from the alpha or dominant dog. Should he try, he’ll face a swift correction. But that’s rarely necessary because in the structure of the dog pack, it is clearly understood who is entitled to what and when.

But what happens when that clear understanding is lacking between a dog and members of his human pack? The results can be a disaster…a dog who guards something against his very owners.

In this article we’ll concentrate on space guarding behaviors. In the dog pack, if the dominant dog wants to walk from point A to point B, he will do it even if he has to nudge a lesser dog out of his way. If the more submissive dog protests, what he is actually doing is challenging the authority of his leader by trying to guard the space he occupies.

The same event may transpire in our homes. Your dog helps himself to a place on the sofa. You either sit down next to him, or try to take his collar to pull him off. Your own dog growls or snaps at you. He’s guarding space. Moreover, he’s stating in dog language that he believes he is dominant to you.

You need to open a cabinet and the dog is blocking your way. You take his collar to move him, and he growls or bites. The same thing may occur when you want to push the dog out a door, pass him in a narrow hallway, or get too close to him laying in his favorite spot.

In many households, the human occupants do not realize that their dog is guarding space until the dog becomes completely out of control. In fact, we excuse the behavior. That’s because too often people apply human standards to canine behavior. Among our species it is impolite to pull someone out of a chair or shoulder them aside when you need something. So if the dog growls when you sit by him on the couch, many people wrongly think the dog is just being grumpy, or that he was too comfortable to be disturbed.

I have actually seen adults chastise children for being “impolite” to a dog for sitting next to him on furniture, or for wanting to remove the dog from their place. People subconsciously try to accept these problems as “quirks” of the dog. Many owners try to just work around the issue by not disturbing the dog under whatever circumstance causes the dog to guard.

Unfortunately, this sends precisely the wrong message to the dog. Humoring him confirms that he is dominant, and is, therefore, entitled to guard more and more space. That’s why guarding behavior escalates for many dogs. Often, I hear from owners who’s dog began to growl at them under very limited conditions, say when being pulled off the sofa. But eventually the behavior escalates to the point where the dog growls when they even get near him on the sofa.

The owner thinks the dog is getting worse. The dog simply thinks he’s getting stronger. For some dogs, dominance is a self-rewarding behavior. You want to remove him from the couch. He growls. You back off. The behavior works. So eventually he growls when you even look at him on the couch. “They just don’t seem to get it,” the dog is thinking. “I’ll have to warn them earlier.”

This can become very problematic for some pet owners, particularly those with young children in the house. Kids often don’t realize that they’re not “supposed to bother the dog.” They just figure they have liberty to safely toddle wherever their little legs will take them. And if you ask me, they should have that right.
Older children must be taught to respect dogs. And younger children must be observed very carefully when they interact with a dog, to be sure they do not accidentally pinch him for example. But no one can expect a two year old child to understand she should avoid Rover when he’s laying on the sofa.
