Wow! I had no idea! Thanks for posting this. My dog can be a little thief! Once he took a $20 bill out of my purse and left a nyla bone in it's place! Imagine my surprise when I went in my purse for cash and instead found a bone. He steals make up, pencils, cigarettes, basically anything he can get away with. Pencils are his favorite! He chews them (he doesn't eat them) and leaves a mess!
