I have 2 dogs, a Doberman & a mixed dog ( half out & half terrier) I’ve been told so. We lived in happiness for 2 years but once we moved the two male dogs began viciously fighting with each other, to the point of where I had to completely separate them, relocating the Doberman to a friends house for then past 3 months. Both dogs are back home now & I’m still keeping them separated. They are both getting neutered next week & I want to know if this will help with the fighting between the two where we can live in harmony together again. Im not going to reintroduce the dogs again until they are both fixed. Also the Doberman can be a bit aggressive with people too, as he has bitten my husband drawing blood twice that I can remember for sure but he also nipped at my child also. If neutering doesn’t work out, what other options do I have ?
