The dog may behave this way because it is afraid of something and is sensitive and unsure of itself. Parents can observe whether there are other dogs around or what happened just now. If the dog's anal discomfort also occurs, it is best for parents to take the dog to the hospital to determine the cause and then treat it symptomatically.

Tip:

The reason why dogs tuck their tails is because they can prevent their scent from being smelled by other dogs. This is generally the case. It happens when there are a lot of dogs.
