Dogs naturally like to scratch the ground. When this happens to a female dog after giving birth, it should be a sign of lack of security. A stranger may have touched the puppy recently. The female dog senses a different smell and is afraid that the puppy will be touched. Hurt, so I want to hide the puppy. It is recommended that the owner enlighten and comfort the bitch to increase the bitch’s sense of security and calm down the bitch.
