Anal Sac Disorders in Dogs

3 min read



If the anal sacs were full, but the material was normal and easily cleaned, your veterinarian may discuss a diet change or dog supplements. Some anal gland issues are responsive to added fiber or different types of dog food. If there is evidence of infection, your veterinarian will prescribe an antibiotic.


Abscessed anal sacs will be opened to the exterior near the anus in order to allow drainage. The anal sacs will then be cleaned and flushed, and prescription pet antibiotics will be infused into them.


If your dog is suffering from chronic anal sac infection, the anal sacs may need to be surgically removed. However, if your dog is suffering from severe fistulation (abnormal openings in the anal sacs), it may benefit from oral cyclosporine therapy.


During treatment, your veterinarian may recommend a diet or supplements to loosen the consistency of the feces. This may make it less irritating to defecate so that your dog does not develop constipation.


If your veterinarian believes your dog’s anal gland issues are related to allergies, she will recommend treatment accordingly.


Living and Management


Your veterinarian will schedule a follow-up appointment three to seven days after diagnosing and beginning treatment for your dog. Your veterinarian will schedule subsequent follow-up appointments as necessary to treat your dog's condition.


If your dog is constantly licking at its anus after treatment, you will need to ask your veterinarian for an Elizabethan collar (recovery cone) to prevent the dog from reaching its anus. Also, contact your veterinarian for further treatment if the anal glands continue to drain after a few days of treatment, or if they appear to be red and swollen.
