In my opinion, responsible and serius breeders should ONLY breed animals that reflect the standard of the breed (including a Yorkie that is not over 7 LB) However, let's see that in a litter of "standard Yorkies" there are 4 puppies and 1 of the puppy is oversized or too tiny, then this dog should be sold to a loving home and be fixed. He should not be used for breeding purpose. I do not have anything against over sized Yorkies (They are loving and have a big heart too
) However, an oversized female should not be bred. Just my opinion and do not intend to offend anyone.
