Dogs bury things with their noses

1. When a dog gets something it likes, it is likely that it will want to hide it for later use, so it will dig the ground with its nose.
2. If the ground has a special smell, especially earthy ground, the dog will keep digging up the soil, which will also be dug out with its nose.
3. If the dog is not satisfied with the food given by the owner or is not very hungry when feeding, it will also hide the food with its nose. When the dog is very hungry but has nothing to eat, it will dig it. Eat in open space.
