Mia's teeth have always been a bit suspect. She's missing one, one grew in sideways, etc. They're TINY little teeth even compared to Summer. This last year or so I've noticed the last 1/3rd or so of her canines are getting see-through? Anyone have any ideas about that? Calcium issue? Chewing on tennis balls too much? You can kind of see it here (looks like staining but it's not). bath6 by Summer_Papillon, on Flickr glasses by Summer_Papillon, on Flickr I've seen dogs with teeth worn way down from tennis balls but not this.
