My doggy is almost 2 years old. The other day I was rubbing her belly, and she had her mouth open... it was SO cute. But... I noticed that she has 2 canine teeth on one said, and just one (like all other dogs I know) on the other side. It doesn't seem to cause her any problems, and it seems like she usually chews on that side. Has anyone heard of this, or know if an extra tooth like that could cause her problems? Any information would help. I'm just worried that something like this could pose a problem in the future.
