You caught your dog doing the booty scoot on your favorite rug and now you're wondering why they do it and how you can get it to stop. Whether that or excessive licking of your pet's hind region is what brought you here, it's likely that your dog's anal glands need attention. While that's probably the last part of your dog's anatomy you'd like to pay attention to, the fact is that anal gland problems in dogs are fairly common and often the cause of dog scooting problems.

Your Dog's Anal Glands

Your dog's hind end includes two small sacs located on the inside of their rectum, one on each side within the muscular wall, says The Spruce. These sacs gradually fill with secretions from sebaceous glands — the same glands found at the end of hair follicles that are responsible for unwashed hair becoming greasy — located inside each sac.

The only real function these anal glands are known to serve is in doggy communication: they're what dogs sniff when they say hello to each other. They also excrete scent whenever your dog goes number two, and may make it easier for your pet to pass stools. When they're working properly, these glands are emptied when your dog does their business.

Anal Gland Problems in Dogs

Unfortunately, things don't always function properly. Soft or small stools don't provide enough pressure to empty the sacs. If the glands fill until they become uncomfortable, your beloved pup scoots across the floor to get relief. When this happens, the glands are what's called impacted, says Preventive Vet.

Not only are impacted anal sacs uncomfortable for your pooch, but if ignored they might become infected and abscessed, requiring treatment with antibiotics. If the abscessed glands rupture, they may need surgery to repair, and your dog might also need pain medication to aid their recovery.

Anal Gland Expression

When anal gland problems in dogs begin to develop, human intervention may be required to provide relief. Impacted anal glands need to be manually expressed, a task that can be performed by a veterinarian, or a vet nurse — some dog groomer who's been trained in the tasked may do this as part of the routine grooming, but if you notice an issue, you should always bring your dog to vet over the groomer.

Manually expressing a dog's anal glands typically involves inserting a gloved finger into the rectum to locate the gland and gently squeeze it to empty its contents. If impacted anal glands become a recurrent problem, manual expression might need to be done on a regular basis. You could do this for your dog at home, but it's best to have a professional teach you how before attempting it on your own. A startled or uncomfortable dog could snap or bolt. The ick factor involved in the task might also convince you it's a job best left to the pros.

What Causes Anal Gland Problems in Dogs?

Poor quality bowel movements can contribute to anal glands becoming impacted, says Petfinder. Constipation and diarrhea can produce stool that isn't sufficient for the task of emptying the anal sacs. Hereditary malformations of the anal glands could also be a cause. Preventive Vet adds that chronic skin conditions, including yeast infections, skin or food allergies or infestations of skin mites, may increase a dog's chances of developing chronic anal gland problems.

Other contributing factors include low thyroid function and obesity. And although it's less common, a tumor could be to blame. It's also possible that unnecessary anal gland expression, as is sometimes done routinely by groomers, could create scar tissue that prevents the glands from being able to empty themselves. If this might apply to your dog, talk to your groomer to make sure your pup's glands aren't being unnecessarily expressed on every visit, which could do more harm than good.
