Shelteez2 hit the bull's eye. There's no such thing as a tea-cup sheltie. The sheltie standard calls for 13-16 inches (as she stated) but oversized shelties aren't hard to spot. It's those collie genes acting up (or so I've heard). I just measured my boys again to make sure that my past measurements were correct (and it turns out I was wrong). Kai, my youngest, is a little over 17 inches. Kaedyn, our older and newest addition, stands at 15.5 inches. I've seen a 12 inch sheltie not too long ago. He was TINY compared to Kai. You'll find alot of variations in this breed. Kai, has floppy ears, is too tall and his coat's wavy. Kaedyn, has near perfect 1/3 tipped ears, a very nice gait and very nice coat.

Just make sure you don't fall for the "tea-cup sheltie" gimick. If anyone says _____ sheltie, don't fall for it. There's only one, the sheltie.
