Ive had a bichon poodle for around 7 years. He doesnt like socializing with people but never had problems playing with dogs. The thing is that I just bought a 8 weeks old female beagle and he just doesnt like her. At first they got along well but now, a week after she got home, he just growls whenever he sees her. She keeps crying because she wants to play with him but Im afraid to leave them alone because I know he might be aggressive sometimes and she is too small to defend herself. I keep thinking that maybe when she grows up, they might get along beause better she has a lot of energy right now and he isnt really playful. Im really frustrated and dont know what to do.
