I would live in a ZOO full of yorkies if I could! Hubby says three is max, but I'm pushing for four!

If one wasn't enough, and two wasn't any more trouble, and the third is already a member of "the family"....why would a fourth hurt??? THAT is what I want to know!!! Two boys, two girly girls...that's all I'm asking for!!! Still working it on hubby! I never got an approval on the first two, why should I on the fourth!!!!!
