My dog is suddenly aggressive to other dogs and resource guarding.

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 3 years and 11 months old | 67 lbs

I have a 4 year old Akita lab mix, she is super happy always and loves people and usually other dogs but since I moved to a different city she has started to be aggressive towards others dogs and has become a lot more food and toy aggressive to my 7 year old Rottweiler (her brother) whom she loves. She has always had a little food and toy aggression towards other dogs but it has increased drastically, so much that she has attacked my Rot a couple times (he never fights back). How to stop this?

Please have Lady seen by a vet to help rule out a possible medical cause for her behaviour. If nothing is found to be physically wrong, seek the advice of a dog trainer who uses positive reinforcement techniques, or a veterinary behaviorist, to help curb this behavior. If left untreated, Lady may injure our other dog, a person or another animal. I would advise keeping her on a leash and away from other animals and people until you have the chance to work with a trainer or behaviourist, and keep her in a separate room from your other dog. You may need to muzzle her to prevent injury. Visit the following link for more information on dog behaviour issues. http://www.dacvb.org/resources/for-the-public/ .
