When we were looking for our puppy it took us forever because we wanted one who was going to be on the BIGGER side of the breed standard. We're young and wanted a dog before real babies. But we know that real babies and our yorkie baby will probably co-exist at some point and we wanted a yorkie that was going to be big enough that he wouldn't get pummeled by a toddler. Maybe it would help your sale of your puppies if you did advertise their size! There IS a market for average size yorkies! Good luck
Oh.. I should mention that we drove over 7 HOURS each way to get our puppy once we found someone who would be honest about his size!
