Why is it That Dogs Have to Bury Their Dog Bones?

Let's see if you have dogs like ours. These dogs bury stuff. That is what dogs do. But normal dogs bury their bones in the backyard somewhere. Not our dog.

Our dog tried to bury a bone in our house. We gave our dog a bone. And what did he do with it? He tried to bury it in his bed. I thought the dog would take the bone outside, dig a hole for it, then cover it up for a rainy day. Not our dog. Our dog tried to bury his perfectly good dog bone in his own bed!

Does your dog do this? Any body know of a good doggie psychiatrist?

And I thought I was nuts.
