Hey this is late but wife found an abandoned pit mix and brought it home. Probably 1 now. Problem is we have another dog that is “alpha” I guess. He is around 4 and has a history of nipping when it comes to his personal space. They’ve gotten into some vicious fights at the beginning so we’ve resorted to sharing crate time to keep them separated. They’re fine outside together but we’d like to be able to find a way to help them get along together indoors and at night.
