We were at the vet today to get Snickers microchip done, they did it when he was neutered only for me to find it in his hair after surgery

So I waited until he got bigger and a bit older. Not a fun experience, I think we were both traumatized...they had to stick him twice! After the first try I told the girl don't do it again go get Michelle 😡.
Anyway there was a woman at the vet who asked what kind of dog he is... Um I think he obviously looks like a yorkie. She informed me "Not with those long legs!" I have AKC papers on him I said well his papers say yorkie... I feel a tad insulted for my pup! So my question is, do all full yorkie a have short legs? He's a big boy at 9 months and weighs 11.9 lbs
