Your pet wants you to read our newsletter. (Then give them a treat.)

Part of having a dog means getting used to thinking about butt stuff. Are they pooping normally? Is their poop runny? Are they straining to poop? Can they poop out that weird thing they ate? Why are they sniffing other dog’s butt’s? Why are they scooting their butt on my brand new Scandi-inspired rug? What is that fishy smell? If you find yourself asking those last two questions, read on to get familiar with dog anal glands.

What are dog anal glands?

Many people use the terms anal sacs and anal glands interchangeably (and we will, too). Anal glands, which are actually anal sacs, are two small sacs under the skin near the anus. They sit at approximately the four o’clock and eight o’clock positions on each side of the anus. These anal sacs are full of anal glands that produce a brown, oily, fishy smelling discharge.

Anal glands will periodically fill with this stinky fluid. When a dog poops, the stool applies pressure on the way out, releasing the anal glands. Normally, anal glands are emptied without any conscious effort from you or your dog. Sometimes dogs will empty their anal glands in times of stress or fear. Your local veterinary staff knows about this possibility all too well.

Although emptying these glands should be automatic, some dogs’ anal glands just don’t drain, even if they’re pooping normally. Dogs can also have difficulty expressing their anal glands if the anal glands become overly full, impacted, or infected. These dogs need a little assistance.

Why would I need to express my dog’s anal glands at home?

Most pet parents don’t need to get involved with their dog’s anal glands (and really shouldn’t want to). But if your dog’s anal glands don’t empty as they should and your vet has ruled out other issues, you may want to learn to express them at home.

For some pet parents, this task is only performed when their dog is showing signs of discomfort like scooting or excessive licking. For dogs with chronic issues, expressing anal glands can become a routine part of grooming. Either way, proper technique can help things go smoothly and save the hassle of unnecessary mess and discomfort. Having a veterinary staff member guide you through the first attempt is a good idea when learning how to express a dog’s anal glands.

Though anal gland expression can be performed at home, some anal gland issues need veterinary attention. If an anal gland is noticeably swollen, the skin over the gland is broken, an anal gland is leaking, or if the gland is firm and cannot be expressed, you should seek veterinary attention. These can be signs of an anal gland infection, ruptured anal gland abscess, or a tumor.

How can I express my dog’s anal glands at home?

When expressing a dog’s anal glands at home, it’s best to come prepared and have all of your supplies handy. Some dogs won’t put up a fuss, but others will let you know that this is not their favorite activity, so it’s best to have a buddy. If your dog is absolutely not having it, or if your dog seems uncharacteristically painful, abort mission and contact a professional.

There are two methods to express dog anal glands — external and internal. Pick the one that is most comfortable for you and your dog.

How to express dog anal glands externally

Gather your supplies: Gloves and paper towels.
Position your dog: Have someone help you if possible. Stand behind your dog and lift their tail.
Locate the anal glands: With a gloved hand and a paper towel, gently grab the area of the rectum, extending about an inch on either side of the anus. You should feel the thicker muscle of the sphincter along with the anal glands, which may feel like firmer lumps on either side.
Express the anal glands: Use your thumb and index finger to gently squeeze the anal glands together until a small amount of brown fluid comes out. This may need to be repeated if both glands are full.
Clean up: Use paper towels to wipe away any fluid that came out. If needed, use a warm washcloth to clean any discharge from your dog’s fur. Dispose of the gloves and wash your hands thoroughly.
Reward your dog: Give your dog praise and treats for their cooperation.

How to express dog anal glands internally

Gather your supplies: Gloves, paper towels, and lubricant (like Vaseline or KY Jelly).
Position your dog: Have someone help you if possible. Stand behind your dog and lift their tail.
Locate the anal glands: With a gloved, lubricated finger, gently insert your index finger about an inch into your dog’s rectum and locate the anal glands. The anal glands are located on either side of the anus (remember: four and eight o’clock) and may be the size of a pea or a grape depending on fullness.
Express the anal glands: Using a paper towel as cover, gently squeeze the anal glands between your thumb (which remains outside of your dog’s butt) and index finger until a small amount of brown fluid comes out. If you do not see any fluid, the gland may already be empty.
Repeat on the other side.
Clean up: Use paper towels to wipe away any fluid that came out. If needed, use a warm washcloth to clean any discharge from your dog's fur. Dispose of the gloves and wash your hands thoroughly.
Reward your dog: Give your dog praise and treats for their cooperation.
