We just added a Bishon (13weeks) to our happy lil family. We have a 1 year old yorkie. For the most part of the day my yorkie barks at him continously and chases him, constantly has the puppy in a submissive position or nipping at him. The Bishon gets back at him too, but not as much. He is soo lovable and calm Im afraid that my yorkie is too hyper for him. Is this normal behavior? When should I been concerned? I know that my Yorkie is a lovable lil guy however he is so stressed... I can tell he has a hard time even eating I have to sit next to him to encourage him to eat. Will this get better?
