Last night, Missy started gnawing at her foot. We were both in bed. She was laying at my feet when she started to attack her own. It was loud enough to make me look up over my book at her. I watch her for a little bit before reaching for the phone. Like any good dog mom, I decided to record it before taking a look at her foot for myself. I rubbed her belly while I inspected her paw. I didn't see anything stuck and the pads of her paws didn't seem overly sensitive to the touch. Right after I put her paw down she stopped with the gnawing. I'm not sure what it was all about. But at least you can take a look for yourself.
