1. If the dog’s anal glands are not cleaned for a long time, they may become inflamed and swollen over time and need to be cleaned in time. .

2. Because the muscles in the pelvis are relaxed or destroyed, abdominal tissues and organs enter the perineum to form a hernia, which requires surgery.

3. It may also be a tumor, such as peripheral tumors, perineal tumors, etc., which require surgical removal.

Tip:

There are many reasons for the swelling under the anus. It is best to take your dog to the pet hospital for examination and treatment to avoid aggravation of the condition.
