Thank you all. Knowing it is a little bit breed related is sort of a relief

My 5 y/o female basenji over the past year has become very aggressive towards dogs that are about the same size or smaller than her. And I believe if she caught a squirrel or rabbit, she would definitely kill it. Could this be a predator thing? No issue with larger dogs. Is this common in the breed? Also, how does one find a trainer that specializes in correcting this specifically in Basenjis. Thanks
