My boyfriend and i just moved in together. I had a dog(huskey and shar pei mix), he had one(whippit and pit bull mix), and we adopted one just recently(german shepherd). His dog had dominance issues, I thought we had worked them all out but now she wont eat with the other dogs. They all are on different dog food brands so in the morning and night they get five minutes to eat their food. The other two dogs understand this and have no problem, but his dog refuses to eat with them and she is starving herself. I think it is a dominance thing because if we put her somewhere else with her food she eats it at once. I don't know what to do, if anyone has any tips, please help!
