Why do dogs like to bury bones?

Animals generally have a special habit, and different animals have different habits. Some animals, in order to prevent a "food shortage," store up some food in advance, and we call this habit food-storing behavior. For example, every autumn shrikes often catch insects, @#@260@#@, frogs, and other small animals they like to eat, stringing them on thorny branches or brambles so they can eat them at any time. The purpose of catching small animals and stringing them up is still to guard against a shortage of food in winter. Squirrels also have this habit.

Dogs also have food-storing habits. In the wild, you can often see dogs digging holes with their paws, burying animal bones in them, and then covering them with soil. It turns out that the ancestors of dogs were wild carnivores, mainly feeding on rabbits and other grass-eating animals. Sometimes they would also go hungry because they could not catch small animals. To prevent starvation, they gradually developed a food-storing habit, burying leftover small animals and other food in the ground. Later, after long-term domestication by humans, food was no longer in short supply. But this food-storing habit inherited from their ancestors has been preserved all along.
