So I have 2 dogs the breed is well lets put it this way not even the beat dog experts can not determ it. They well are born from a street dog their brothers but one is a little bigger then the other and both male. The problem is that they fight a lot and do not get along quite a lot. The strange thing is that they grew together and after 2 years they could have decided who is the alpha but they did not. Any advice from other dog owners?
