Aggressive Dog Behavior

How do I stop aggressive dog behavior?

Hi, I have an 8 month old Jack Russell called Buster. All of a sudden he has started to growl and snarl he does not do this all the time it seems to be possession thing. He has not bitten anyone but I am starting to lose a little trust in him.



Vet suggestions to stop aggressive dog behavior

Hi Sarah,

Now is the time to stop this behavior! The longer it goes on, the harder it is to deal with. If Buster is only starting to act aggressively around his possessions (e.g., toys), the first thing you need to do is to teach him the command “drop.” Do this by saying “drop” and then offering him a treat (he’ll have to drop the item to take the treat).

As he learns the command, wait until he has dropped the item and lets you pick it up before you give him the treat. Of course, do not attempt to take a possession away from him if you are at risk for getting bitten.

I’m concerned that Buster is starting to act aggressively at only eight months of age. This could be the first sign of more problems to come as he matures. Talk to your veterinarian or a veterinary behaviorist about behavioral modification options.

Best of luck,

Jennifer Coates, DVM
