Does your dog hide toys or bones around the house?
I know that this is normal behavior for dogs but Basil's never done this before. But yesterday we gave him a new chewy bone and he keeps pushing into corners, under furniture, etc. And then he rubs his muzzle on the floor to push "dirt" on top of it. I know this is something that a lot of dogs do instinctively but he's never done it before so I find it hilarious.
