That just means that there is more to LOVE !!
I love my Porky Yorkies . .
A pups weight can never ever be predicted. I myself have had pups that reach 3-10 lbs form the same parents (6-8 lbs) different litters and others from different parents ranging from 9-10 lbs having pups that range in the 10-18 lb range. Its all a matter of genetics. Those genetics from larger breeds that come from the Yorkie heritage can pop up anywhere in the line. Plus there is always the feeding habits that can have an effect on the weight of the pup.
