Dogs

We often see dogs in movies or cartoons having the habit of burying bones. Pet dogs may not be able to bury their bones in this situation, but what I want to tell you is that this is the nature of dogs. If one day you find your dog burying bones, don’t blame them. , dogs bury bones to store food!
Animals generally have a special custom, and different animals have different customs. In order to prevent "food shortage", some animals will store some food in advance. We call this habit food storage. For example, shrikes often catch insects, lizards, frogs and other small animals they like to eat every autumn, and hang them on thorny branches or obstacles for easy consumption. Their method of catching small animals and hanging them on strings is to prevent lack of food in winter. Squirrels also have this custom.
Dogs also have the habit of storing food. In the wilderness, you can often see dogs digging holes with their paws, burying animal bones in them, and then closing them with soil. It turns out that the ancestors of dogs are wild carnivores, which mainly feed on rabbits and other grass and other animals. Occasionally they starve because they cannot catch small animals. In order to prevent starvation, they gradually developed a food storage habit of burying leftover small animals and other food in the soil. Later, through long-term training of humans, of course there was no shortage of food. However, this food storage custom inherited from our ancestors has been maintained.
