Resource Guarding – Dog growls to protect his bone

How do you safely take a toy or bone away from a dog?

Does your dog exhibit aggressive behavior when he has a bone or toy? This issue is called Resource Guarding and if not addressed, can escalate into dangerous behaviors like biting.

From an evolutionary standpoint, dogs developed this behavior for obvious reasons. If a dog didn’t protect high value objects like meaty bones from theft, it would starve, pure and simple!

In practical terms, that toy, bone, or high valued object is rewarding to the dog, and having it taken away is an undesired outcome.

Forcing the dog physically to give up the toy will cause this problem to escalate, up to and including severe biting. So how can we address it safely?

As a positive reinforcement dog trainer, you must make the behavior of giving up the toy or bone a rewarding behavior. This is commonly done by trading objects with the dog with food – after all, the dog can’t guard a toy while simultaneously taking food from your hand.

Furthermore, if every time a toy or bone is given up and it’s put away, there’s no incentive for the dog to ever give up the toy, so its important to trade for food, and then return the toy to the dog. This creates a win-win situation where there’s no downside at all to giving up the highly valued object.

If you trade for food, and return the toy enough times, you’ll find your dog actually looks forward to releasing the toy as you approach. Its at this time we can put the behavior on cue with “Out” or “Drop It”.

If your dog has developed a serious case of resource guarding, where he starts growling and even biting as you approach, it is absolutely critical that you get professional help with this work as the risk of eliciting a dog bite is very high.

Whatever you do, don’t force the dog to release the object. This only teaches the dog that he was right to guard the item in the first place, and will increase the severity of the guarding and increase the severity of his aggression response. He’ll progress from guarding looks and body language to growling, and ultimately may resort to biting to protect the object.

Start early with your puppy to practice trading. If your adult dog is growling or biting, get help right away with a trainer or behaviourist that uses positive reinforcement to teach the dog that giving up toys is a fun and rewarding game.

  1. Thanks so much for this, we were seriously worried about our puppy after some uncharacteristic nastiness. Practiced drop and it worked great. Need to be consistent with it but she’s doing well so far. We tried time out which did get her to calm down, but nearly got a nasty bite in the process. This worked much better!

  2. I know this is an older article but I’m glad I found it. My 8 month old puppy just started to guard an edible chew. She had never been aggressive about it before but just suddenly started to growl and bite at my son when he touched her while she had it. She did the same to me and I was very surprised. We had started to trade objects she wasn’t supposed to have for a high value treat but I never thought to do that with her edible chew. I think that’s a great positive solution. I don’t want this to escalate.

  3. I am fearful of the outcome for my dog. She is a little over a year. If she finds a food bone or a treat bone she is in full attack mode and has bitten my nephew. With her bowl food I’m not sure if she will attack I have rubbed her and such while eating. The other thing is she will miss meals, her choice. She is fearful sometimes stressed and anxious lots of changes around here but I try to keep her things a routine even when we travel. Please help me. There are other underlying issues as well I can’t even teach her to have an attention span longer then a few seconds.

  4. I just adopted a 2 year old Bernese Mt dog and he has growled at me when I want him to move, like he got in the front seat of my car and I nudge him to get in the back and he growled. Or I tried to make him go in another room with his toy and he snapped at me. Ive only had him for 3 days but I dont know what to do. Should I out him down ?
