He is adorable! He has such intelligent eyes! He looks like a yorkie to me, but I think he also looks like he might have some havanese mixed in? (I'm basing this on the shape of the muzzle and shape of the eyes, looking at pics online) We have lots of members with purebred "teapot"

yorkies that are 15+ lbs, so it is quite possible he is all yorkie. I can imagine that with kids, a larger, sturdier yorkie would be much more preferable, for safety reasons.
