I have a 4-year-old rescued Chihuahua. He is growling and sometimes charging at you. I would like him to be nicer to Grandkids and others. He also has issues at times peeing in my house. DJ is a sweet dog and loves belly rubs but here recently growls if I do rub his belly now. Before he absolutely loved it. I don't know what or how to train him not too.
