Everything I read says make sure you contact a reputable breeder for a Doberman to ensure you get one without aggression. Apparently bad breeding can cause an aggression issue from what I understand. How do I find a reputable breeder, preferably in PA near Pittsburgh or even West Virginia. I want a Doberman that can be good around cats. What are good questions to ask about that or about the breeder at all? I have been raised with dog my whole life, and the one dog I have always wanted was a Doberman. However, when I moved away from my parents, I never lived where I could have a dog, so I got 2 cats instead. Now I have a place where I can have a dog and I still want a Doberman. I have researched the dog and understand I need to train and socialize it extensively, and that the dogs are very hyper and known as velcro dogs. I have seen lots of accounts where Dobermans can live with cats and be friendly, and my best bet it to raise the dog with my cats as a pup. My one cat seems fine with a strange dog unless it chases him, then he hides. The other cat’s only introduction with a dog was one of my old ones soon before she passed. The dog was partially blind and very aggressive with other animals, always was since she showed up under our car one day, my cat sat above her and would paw at her head, trying to torment her, but would for the most part stay away and hiss at the dogs. Once they get used to an animal they seem to be okay with them, so my question is what can I do to try and make sure the Doberman is ok with cats?
