The Tooth Loser

Dallas is losing teeth. We expected she'd be growing new teeth, but for some reason I never realized that meant losing baby teeth. Check out the bottom right tooth she lost - there was about a 4 hour span in between these two photos. In the morning she had the tooth. In the afternoon, it was gone.

Where do all these teeth go? Do dogs swallow all these baby teeth in their daily meals? Is there a bunch of buried baby teeth in my garden, or wherever they fell in the yard? Maybe I should check the vacuum bag.
