I happen to have a very tiny yorkie that I bred. (unintentionally) He is going on 6 months old and weighs in at a whopping 1 lb 8 ozs. I had 6 from this litter and only 2 were this tiny. I lost the little female but managed to save the little boy after 2 months of 24/7 every hour on the hour getting up to nurse him and keep him from crashing. Mom and Dad both weigh 5 plus lbs and I never got tiny's before this. I retired Mom after this last litter as she was going on 7 years old. My little Pocet Rocket is now very healthy. I'm a vet tech, so I take him to work with me every day, so he gets to see the vet A LOT!
So I try not to judge people unless I know they are breeding for tiny's like JDEAN does. I thinks it's awful to try for these tiny ones, but I wouldn't give my little one up now for anything! BTW, I didn't sell him because I was afraid that whoever bought him would not be abl;e to take care of him the way he needed to be and didn't want someone to buy him and then have him die and them be heartbroken. I try to be responsible and breed good pups, but sometimes.......things just happen for no good reason. Never had a problem with this mom and Dad before so think it was just a fluke that he was so tiny. The other 4 pups that lived were all "normal" size.
