Why do dogs like to bury things? It turns out these are the reasons

Dogs kept in the yard often like to dig a hole and lie down when it is hot in summer, and if there is leftover food they also like to put it in the hole and hide it. This is because in wild times dogs often dug a hole about 3 m wide on hillside slopes to live in, and their hoarding habit was also formed at that time. In order to keep the hole used for sleeping clean, they will also choose another place to defecate.

Animals generally have a special habit, and different animals have different habits. Some animals, in order to prevent a "food shortage," will store some food in advance, and we call this habit food-storing behavior. For example, every year when autumn comes, shrikes often catch some insects, @#@260@#@, frogs and other small animals they like to eat, and string 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 the food-storing habit, and in the wild it can often be seen that dogs use their paws to dig holes, bury animal bones in them, and then cover them with soil. It turns out that the ancestors of dogs were wild carnivorous animals, mainly feeding on rabbits and other grass-eating animals. Sometimes they also went hungry because they could not catch small animals. In order to prevent hunger, they gradually developed a food-storing habit, burying leftover small animals and other food in the ground. Later, after long-term domestication by humans, although food was no longer scarce, this food-storing habit inherited from their ancestors has always been preserved.
