Does your dog like to do the butt-scoot across the living room floor? Does he spend just a little too much time investigating his hindquarters? While it's possible that he just has an unhealthy obsession, it's also likely that he is having some trouble with his anal glands.

A dog's anal glands are situated on both sides of the anus, underneath the tail. The glands contain an odorous material that can be used to mark territory or display fear. These glands often become impacted, meaning that they stop working and become overfilled. This can cause noticeable pain, which causes the dog to attempt to express the glands by rubbing his hind end on the floor. The glands can also abscess, causing a foul odor and excessive liquid secretion.

Anal gland problems can occur in both males and females, and on rare occasions cats can have problems as well. Obese pets tend to have more problems with their anal glands, so weight maintenance is a must. Many smaller breeds commonly have anal gland problems, including miniature Poodles, Dachshunds, and Chihuahuas. Predisposing facors include chronically soft feces, obesity, or recent diarrhea.

Most dogs express their own glands simply by going to the bathroom. Impacted anal glands can be expressed, either by yourself or your veterinarian. Preventative measures can be taken, such as making sure that your pet has enough exercise and plenty of opportunity for bowel movements. If you are unsure if your dog is having problems with his anal glands or if you have any questions, please contact your veterinarian!
