Anal Glands on Dogs: What You Need to Know

Anal Glands on Dogs

Anal glands are small sacs located on either side of the anus in dogs. They produce a foul-smelling fluid that is used to mark territory.

Function of Anal Gland

The anal glands help dogs to communicate with each other. When a dog is scared or excited, they may express their anal glands to leave a scent trail.

How to Express Anal Glands

If your dog's anal glands become impacted or infected, they may need to be expressed. This can be done by a veterinarian or a groomer.


Signs of impacted anal glands include scooting, licking the anus, and excessive gas.

Signs of Infected Anal Glands

Signs of infected anal glands include redness, swelling, and pain around the anus.

When to See a Vet

If you think your dog's anal glands are impacted or infected, see a veterinarian right away.


You can help prevent anal gland problems by feeding your dog a healthy diet, keeping their anal area clean, and exercising them regularly.
