I have 4 Yorkies, 3 are from the same parents, different litters, they now weigh 7-16 lbs. Also don't give up on them liking each other. When I brought Sassy my 4th one home the other 3 really disliked her. I thought I would have to return her, but now she is the youngest and smallest but bosses her brothers around. Hang in there, it will get better
