Why do dogs always rub their buttocks?

Dogs that keep rubbing their buttocks may have parasites. Parasitic infection can cause anal itching in puppies and is also one of the reasons why dogs rub their buttocks. Owners can observe the dog’s feces to see if there are eggs or worm bodies. Puppies need to be dewormed internally and externally regularly to avoid affecting their health. If the dog's anal glands are not cleaned in time, the dog will also rub its butt. After squeezing the dog's anal glands, the dog's butt rubbing behavior will be improved.
