Why is it that the expensive bone you bought from the Pet Store is taken and instantly buried in the garden? Is it not something he would enjoy chewing? So why instead of settling down for a nice long chew he immediately rushes outside to dig a hole and then bury the bone.
In simple terms it is a survival instinct. Burying food away from predators to be dug up and enjoyed later is something wild dogs will do. When food is plentiful then storing some for later makes good sense. The powerful nose of the dog ensures that he can always find his buried treasures. The high concentration of acid in a dog’s stomach kills the bacteria that multiply in a raw bone so that when it is dug up they can enjoy it safely.
The will often d this with a fresh raw bone, lots of dogs like the bone to rot a bit before eating, it seems to increase their enjoyment however gross it is to us.
