Mine range from 3.5 to 11 pounds. I love them all equally. The big boys, Teddy and Quattro, are just like babies to hold. They can hug back, too. The little ones can't do that. I think I worry more about Robyn because she is small. She usually runs under a chair when anyone walks near her, then pokes her little head out to see if it is safe to come out. The littler ones are easier to bathe and dry, but the big ones are easier to brush.
