Personally i think it has to do with frame not weight. Daisy's mom was barely 4 lbs and she whelped 5 puppies with no problems. Peeka's mom was also 4 lbs and she is small and she had 5 puppies to with out complications. But i don't feel you should breed for super tiny dogs. I mean 4 lbs is pushing super high risk if you don't know what you are doing and even if you do know what your are doing it's dangerous. I would never condone breeding under 4 lbs nor would i ever buy a puppy that came from a mother under 4 lbs. JMO |
