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 Glands

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.

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.
