Oh I don't know too much about them but one of my customers breeds them and he brought through a sweet little girl today so that I could hold her and play with her a bit, She was very tiny and seemed very sweet. Just a little ball of fluff. If my daughter didn't have allergies, I would consider one, esspecailly because I get to see his everytime I work, and they are always sweet and well mannered. The puppy was a real treat to hold she just snuggled right up in my arms
