Only 3?
I have 3 right now (actually a Dachshund, a Jack Russell, and a Yorkie) and am getting another Yorkie in a few weeks. I think there are "pet people" and those who have not yet become "pet people." Those who have not yet become enlightened sometimes do not understand or appreciate our enthusiasm for our pet families. When the right pet comes along and trains them up, it will be a different story!
Until then, they should probably MTOB though.
