How to stop my 4-month-old puppy's food aggression towards other dogs?

Updated on September 23rd, 2025

Pet's info: Dog | Border Collie | Female | unspayed | 3 months and 21 days old | 6.6 lbs

Hi! My boyfriend’s puppy is almost 4 months old and has been showing food aggression towards my dogs (13 and 10 years old), when they approach her dog food. As well as while they are around the the human food table, they all get aggressive with each other (I always need to separate them while she attacks them). How can I help the puppy not to get agreesive with my dogs, with food around?

Food aggression and resource guarding is common behavior and since she is young I think you could have good success with a little work. Your goal will be to make her think that your approach and eventually the other dogs' approach is a very good thing that results in treats. You should start by choosing a treat that will be even more appealing than her food, and tossing them in her bowl from a safe distance where she feels safe. If she seems comfortable with you close to the bowl you can stay close and put treats in the bowl when you are nearby. Eventually you want to try having your other dog nearby on a leash but at a distance where she is not threatened and then toss treats to her - you should gradually decrease the distance as she gets used to it. If you're having difficulty you should talk to your vet about referral to a behaviorist.
