The woman has a dog, but because she is busy at work, she is rarely at home. Occasionally one weekend, the woman was lying on the sofa watching TV, and the dog was sitting next to the woman obediently. When the woman turned around, she found that the dog was biting her hind foot.

The woman was startled, thinking that the dog was hurting itself, and quickly pulled the dog's foot out of the dog's mouth. Fortunately, there was no external injury on the dog's foot. After waiting for a while, the dog put his foot in his mouth again.

The next day, the hostess saw the same situation again. She felt that her dog must have some strange disease. I quickly contacted the nearby pet hospital and took the dog to see a doctor.

The doctor looked at the dog’s feet and mouth and found that the dog’s body was not seriously injured. Well, it is a hobby for dogs to put their feet in their mouths, just like people, it is normal. The hostess said she couldn't accept the dog's habit of heavy taste. Dogs have really unique hobbies. Do dogs really have their own personal hobbies like people?
