Very enlightening that this happens so frequently.
I breed yorkies but only for three years now. I havent had these kind of way off weights, they tend to stay pretty close to the weight scale....I have been off but never (so far!!!) by more then a lb (that I know of). I have never had a puppy grow double or triple what I estimated but you all are proof it can happen. Some of the babies that have homes are young too so who knows they may take off and be as big as a great dane at adulthood...........haha
......Lord I hope not!
Anyway weights are always a guessimate, its nice to know others experiences because they are much different then mine so far.
I feel kinda bad because I didnt discourage the purchaser from pursuing action if she felt she was lied to. I still doubt the parentage of the puppy but I only know what Ive been told and I dont know the breeders story.
