I have had Isabella since she was 10 weeks old, she is around 4 1/2 pounds at the moment. My older Yorkie (Murphy) is 4 1/2 lbs at 5 yrs old.
He does not seem to mind her being here, but she wants to play alot with him and he is not into playing that much we guessed. He does just seem to tolerate her, as he does not bother with her too much. She is always nipping at him and then running, she wants him to chase her, but he just pretty well trys to stay out of her way. I feel bad sometimes, as this was his house for 5 yrs, now he has to share it and us...

) not quite sure he loves the idea.
When do you wing a puppy off puppy food?
