Hi everyone! Just joined. I have an 8 year old GSD that I just moved to New Orleans from Orlando Florida. Been wanting to join this group forum for a while. But now that I’m living with a new girlfriend who has a small Chihuahua and I need my GSD to behave properly for the first time around a smaller dog. My GSD is very very well behaved he just has this stomping issue on the small dog that could cause harm to the little guy. Not to mention this action really really upsets my girlfriend, she may ask us to leave the house. Can someone help me? Please? I don’t wanna be in the streets with my pup haha.
