The weight issue is a lot more complicated than just the weight of the female and the male.
For instance, you could have a male that was 3 pounds that came from parents that were say 8 and 10 pounds. Then his genes would actually be bigger than say a 5 pound that came from 5 and 6 pound parents. Of course, you would also want to look at the grandparents.
If you take a 9 pound female and breed it with a 3 pound male (with small lineage), the pups could be within the standard of 4 -7, but they could go on to produce pups out of the standard. That is why there are so many surprises with Yorkies.
The most reputable way to breed is to breed dogs that are within a pound of each other (currently and lineage). |
