I think Tatiana is one of the shorter ones. She has short legs, and relatively thick body. She's a yorkie midget.
Weight: 3 lbs (and about 3 oz, I think)
Height: 5-1/2"
Length: 8"
Neck: 7-1/2"
Girth: 12"
Look at the difference between her short legs and her girth. It's laughable. This is one of reasons why it's difficult to find dog clothes that fit her. Every piece of clothing I purchased I had to alter to fit her.
Right now, I have a bag of dog clothes to work on. I think there's about six pieces.
