hello and welcome to yt! i believe there are dna kits you can purchase to confirm if your baby is full yorkie. i think you should start there before going after the seller. some yorkies are up to 15 pounds.....they come in all sizes so it is not unusual for them to be tiny small med and large. good luck and im glad you love ur baby no matter his size or pure/mix breed.
