In the world of people, our vision is the primary sense that helps us understand our environment. For our pets, their primary environmental sense is smell. This month, we focus upon the delicate topic of your pet’s anal glands — what you need to know and how to help keep your pet healthy.
Anal Glands
Your pet’s anal glands are two small sacs that contain a scented liquid. They are between your pet’s internal and external anal sphincters at approximately 4 o’clock and 8 o’clock. When your pet defecates, the pressure of the excrement exiting the body places pressure upon these two glands causing the liquid within to be expelled onto the passing feces.

Issues
For a healthy pet, most owners are unaware of the existence, function or role of the anal glands. A firm, healthy bowel movement tends to fully excrete all of the fatty or sebaceous liquid within the glands.

- Overactive glands producing excessive liquid
- Temporary duct blockage
- Chronic duct dysfunction — due to a past trauma, infection, inflammation or allergy
- Breed disposition — typically smaller breeds or those with smaller ducts
- Sphincter dysfunction
- Pet obesity
Identification
One of the most common indicators that your pet is having an anal glad issue occurs when they “scoot” on the ground, grass or carpet. This indicates a level of discomfort as they try to expel some of the anal gland liquid. Additional signs include:
- Excessive licking or biting of the anal area
- Lack of hair around the anus (previously chewed away)
- Discomfort while walking or sitting
- Excessive straining while defecating
- Sudden release of a foul (fishy) odor
- Bleeding and/or swelling near the anal region
Failure to obtain treatment can result in the development of soreness, swelling, infections/pus or abscesses that produce pain, burst or bleed.

Remediation
For some pets, a periodic (often monthly) manual expression of their anal glands is required to keep them healthy and comfortable. During your pet’s wellness checkup, we will examine their glands to determine their current state of function and expression. As required during the annual or special-purpose visits, our veterinary technicians will carefully clean the area, wear sterile gloves, apply lubricant, and gently expel the contents of the glands in a pain-free manner. While often messy, this tends to deliver immediate relief to your pet. It is important that the process be performed properly (from the inside of the gland, outward) to avoid trauma to the area which can lead to additional anal gland issues.

Prevention
While some pets and breeds may be predisposed to anal gland issues, prevention through a high-fiber diet, careful grooming/hair trimming of the area, regular cleaning, and the periodic inspection for inflammation can help reduce the incidence and magnitude of potential issues. Of course, keeping your pet active to maintain a healthy weight can also help reduce the likelihood of anal gland and other health-related issues.
