Ozzie weighs 13.5 as of his last vet visit a few weeks ago.
Doesn't seem like he weighs that much until you pick him up! He has gained a pound or two since getting neutered last year, but he's still not obese. (Vet marks chart "large" over heavy and obese options.)
His parents were both small, 6-7 pounds. And our first Yorkie never weighed more than 7 pounds his whole life.
I am with all of you who prefer the "bigger" guys. And the comment about being more "durable" is dead on. Our first Yorkie barely weighed 2 pounds when we brought him home and I was terrified. Ozzie weighed 3.3 at 11 weeks when we got him but doubled that by six months.
No offense, but I've gained between 10 and 15 pounds since Ozzie came home in 1997. I sure hope he doesn't want to trade me!
