I know small breeds can have random teeth issues.. I've just never experienced it. I brought a 13 month old home tonight.. and well, he's lacking teeth. Not a lack of room as his mouth isn't that small, but there are a ton of gaps.. Doesn't seem to be hurting him, he eats happily. Doesn't really want me to examine his mouth but he has tiny nubs where canines should be. Not worn down, just not full canines.. Is this 'normal' in some breeds? He's on the rather large side of the breed.. but his teeth are still lacking.
