If we look around at most breeds (even most animal species in the world - including people) -- the males are always larger than the females......making it natural for females to usually breed with males that are larger than they are.....and the Yorkie's small size shouldn't negate this rule.
The Yorkie is a small dog - but mammals much smaller than any dog breed successfully and almost always with the male being larger than the female.
However, because of the wide variation in Yorkie sizes (more so than most species), it certainly should be our responsibility to breed males with females that are close to the same size.
Depending on the size of your Yorkies, I doubt many of you professional breeds worry about your males being a pound or two larger than your females. This would often be only the natural difference in their weights and shouldn't cause a problem.
PLUS - Wouldn't it be difficult -- to always breed females with smaller males. A geneticist would have fun with this one.
***** Then there's my dog's family.....to the other extreme. His mother was 12 pounds. His father was 4 1/2 pounds. My dog is 13 pounds. He has a brother that weighs 5 pounds and another brother that weighs 6 pounds. (I just got the "big one.") And - believe me - when I picked my pup out - all three puppies were the same size. Mine just grew and grew and grew!!!!!
