My dog is aggressive towards people and other dogs. What should I do?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Female | spayed | 2 years and 7 months old | 50 lbs

This is my dog Asha, around 18months she decided she no longer wanted to be social with new humans or dogs. She gets extremely aggressive: lunging and angry barking towards dogs and humans alike. I took her to a trainer, she is more obedient with me but still reacts the same way to others. She is on 20mg of Lovan but I have not noticed a change in her behaviour. Last night she jumped up on someone and snapped in their face. I want to help her before her behaviour leads to something much worse.

I'm sorry to hear Asha isn't responding well. If you've only worked with a trainer, i would suggest seeking out a veterinary behaviorist instead. They are veterinarians that specialize specifically in behavior, and work on both medication and training adjustment to help with behavioral issues such as aggression. It may be that a vet behaviorist can help adjust Asha's medication and provide better training options and desensitization that is better. As with any issue, it does take time, and complex issues such as aggression can sometimes take a very long time, or only see small improvement instead. It could be that Asha is never truly comfortable with other pets and people, but a complete evaluation from a professional is needed to determine this.
