Why Does My Dog Keep Licking His Bum and Tail?

Updated July 3, 2025

Dogs are endlessly curious and wonderfully complex companions. They explore the world in ways that may seem unusual to us—one such behavior being when a dog licks its rear end. While this might feel awkward or concerning for owners, it’s a normal part of canine behavior that can carry several meanings.

By gaining insight into what drives this habit, you can better support your dog’s well-being, comfort, and overall happiness.

A Natural Instinct: Why Dogs Lick Their Rear

Licking is a deeply ingrained behavior in dogs, just like sniffing or tail-wagging. It’s one of their primary tools for self-care and communication. While humans may associate cleanliness with soap and water, dogs rely on their tongues.

In many cases, this licking is simply part of normal grooming, especially for long-haired breeds that may struggle to keep certain areas clean. Dogs may also lick to relieve itchiness or minor irritation, just as we might scratch an itchy spot.

It’s important to observe the frequency and context. Occasional licking is generally harmless, but if it becomes excessive, it may be a sign that your dog needs extra attention or care.

Common Causes for Increased Licking

When a dog begins licking its rear more than usual, it may be reacting to something in its environment or a health issue. Below are some of the more common reasons to be aware of

1. Allergies

Environmental allergens, such as dust, pollen, or certain foods, can cause skin irritation, leading to increased licking. If you’ve noticed other signs, such as redness, scratching, or ear issues, it may be worth discussing allergies with your veterinarian.

2. Parasites

Fleas, ticks, or intestinal worms can cause discomfort near the tail or anal area. A visit to the vet for proper testing and treatment can quickly resolve the issue.

3. Anal Gland Discomfort

Dogs have small anal glands that sometimes require assistance in emptying. If these glands become full or irritated, your dog might lick to find relief. Scooting on the floor is another common sign that these glands need attention.

When Licking Points to a Health Concern

Sometimes, licking is more than a behavioral quirk—it’s a signal of an underlying issue that needs medical support. Being aware of additional signs can help you act quickly.

1. Infections

Bacterial or yeast infections in the area around the rear can cause discomfort. These typically require medical attention, and your dog may exhibit signs such as swelling, redness, or a foul odor.

2. Skin Conditions

Dogs, like people, can suffer from dermatitis, hot spots, or dry skin. These issues may stem from diet, environmental triggers, or even grooming products.

3. Digestive Upset

Occasionally, tummy troubles can manifest as excessive licking of the rear end. If your dog is also experiencing diarrhea, vomiting, or a loss of appetite, it’s time to reach out to your vet.

When to Seek Veterinary Support

It’s perfectly normal for dogs to lick their rear occasionally, but there are times when it’s best to call in professional support.

• Persistent or excessive licking that causes redness, hair loss, or sores.
• Other symptoms, such as vomiting, scooting, or changes in bathroom habits.
• Sudden behavioral changes like withdrawal, restlessness, or sensitivity.

Gentle Ways to Help Your Dog

If you and your vet determine the licking isn’t due to a medical issue, there are several ways to help redirect or reduce the behavior.

1. Positive Reinforcement

Encourage your dog when they choose not to lick. Offer treats or affection to reinforce the behavior you’d like to see.

2. More Enrichment

Ensure your dog’s routine includes regular walks, interactive play, and mental stimulation to keep them occupied and content.

3. Pet-Safe Deterrents

There are vet-approved sprays that may have an unpleasant taste but are safe for pets. These can discourage licking, but always consult your veterinarian before using any product.

How Can Pet Insurance Help You if Your Dog Needs Treatment?

Pet insurance can be a valuable tool in managing the costs of treating a dog’s veterinary expenses. By having a pet insurance policy in place, you can have peace of mind knowing that you can provide medical care for your furry companion without worrying about the financial burden. Pet insurance can help cover the costs of veterinary consultations, diagnostic tests, medications, and even specialized treatments if required.

Reimbursement

This method is the most common for pet insurance companies. You pay out of pocket for the veterinarian bill, and then the insurance company reimburses you for what’s covered under the insurance plan. The steps look like this.

• You pay the vet bill after your dog’s visit.
• You fill out the pet insurance claim form.
• Submit the claim form and other required documentation to the insurer.
