Oh how sad I am for you !!
I totally undestand that you have been looking for a puppy that you can carry around in your purse. I am sad that you have been taken advantage of. Nobody can guarantee the size of a puppy !!!! Also if you purchased a puppy as a purebred you are entitled to receive the registration papers. Please report the breeder to the kennel club that he/she belongs to if you do not receive the registration papers. CKC members have to register their puppies in the new owners name within 6 months of purchase. .................. Experienced breeders can predict the size of their puppies based on previous litters. This takes a lot of time, effort and skill. By skill I mean that the breeder has used both parents, keeps a detailed record of every litter they raise and follows the puppies to adulthood. Still, there is never a guarantee. The puppy weight chart is just a guide. If you double the weight at age 12 weeks you will likely get fairly close to the adult weight .That only works if your puppy grows up in a healthy environment. Some "breeders " will use inaccurate scales or withhold food so the puppy is small at purchase and when you take him home he will gain weight fast. If size is very important to you bring your own sensitive digital kitchen scale and weigh the puppy yourself before you purchase...................I hope that you will still love your little friend. Health is more important than size. There are a lot of good breeders out there and I have been lucky to find honest and knowledgeable people that were willing to share information and experiences. My motto goes " If there is room for one Yorkie there is always room for another one ". I have posted some links on my web site
