I have a 1 year old schnauzer and he’s usually good with adults, he’s very attached to me and prefers not to be with anyone else but he’s still good with them either way. When he’s around my 1 year old niece he barks so aggressively and wants to bite her and it worries me because I’m pregnant and I’m scared he won’t be good with my baby. He can’t be an outside dog because I have a pitbull and they’re great with each other but sometimes my pitbull gets annoyed of him and wants to bite him. Any advice on what I can do?
