I have two female dogs they are two weeks apart in age. one is a shih tzu and the other one is a schnauzer/terrier mix. they do not seem to get along. once we get them together they fight. I want to know how to stop this. princess (shih tzu) hardly barks and is very easy going but Angel (schanuzer/terrier mix) is always whinning and barking. if we have her inside the house in the room she whines and barks if we let her out she still does the same. I just need this two dogs to get along because they need to live with each other regardless. I love them and will not get rid of any of this two but need help to get them to get along.
