Huff is becoming very bratty. He is an all around attention hog! Since we opened our dog grooming shop, he is always barking at the other dogs if we won't let him play with them. It is so annoying! He also barks at people when we don't let him get too close. I know I am making it sound like he is aggressive, but he isn't. He is just way too friendly! He starts getting all over them and their dogs (in a friendly way). He also starts smelling crotches and people don't like that. So, what I am asking is how can I stop this behavior and start greeting people calmly?
