It can be concerning when a dog keeps licking its anus after grooming. While occasional licking can be normal, persistent or excessive licking may signal irritation or even an underlying health issue that needs attention.
We outline the common reasons why a dog keeps licking its anus after grooming, what you can do at home, and when to seek veterinary help.
Dog Keeps Licking Anus After Grooming — Why It Happens
Dogs may lick their anus after grooming due to irritation, residual cleaning products, anal gland issues, allergies, or minor injuries. Sometimes, the grooming process itself causes temporary itchiness or sensitivity. In other cases, licking may point to something more significant, like infection or inflamed anal glands.
Understanding why it happens helps owners know when it’s normal and when it needs veterinary care.
Dog Keeps Licking Anus After Grooming: Common Causes
Anal Gland Irritation
Dogs have anal glands that can become irritated during grooming, especially if they were expressed or pressed accidentally.
When these glands are sore or inflamed, a dog may lick excessively in an attempt to relieve discomfort.
Signs include scooting, swelling around the anus, and a strong, fishy odor. Anal gland problems should not be ignored, as they can progress to painful abscesses.

Skin Irritation From Grooming Products
Shampoos, sprays, or wipes used during grooming sometimes leave behind residue that irritates sensitive skin around the anus. Even mild products may cause redness, dryness, or itching in dogs with allergies.
Excessive licking soon after a grooming session can indicate that the products used did not agree with your dog’s skin.
In some cases, fragrance or alcohol-based ingredients are the culprits.
Clippers or Scissors Causing Minor Injury
Clipping hair around the anus, often done for hygiene reasons, can accidentally nick or scrape the skin.
These small injuries are often difficult to see but can cause significant irritation, leading to licking.
Even without cuts, clippers may leave razor burn or irritation from close shaving. If the area looks red or the dog reacts to touch, grooming-related injury may be the cause.
Allergic Reactions
Some dogs are prone to allergies, and grooming products or even environmental triggers (like pollen or dust on grooming tools) can set off a reaction.
Allergies often cause itching around multiple areas, but the anus may be particularly affected after grooming.
Excessive licking combined with scratching at ears or paws suggests a wider allergic flare-up.

Post-Grooming Stress or Anxiety
Not all causes are physical. Some dogs experience stress during grooming and may develop repetitive licking behaviors afterward.
Anxiety-driven licking usually comes with other nervous habits, like pacing or shaking. While mild, it can worsen irritation around the anus and lead to secondary problems if the skin becomes raw.
Parasites or Infection
Sometimes, grooming brings attention to an existing issue like worms, fleas, or yeast/bacterial infections near the anus.
A dog with parasites may lick persistently, regardless of recent grooming. If you notice swelling, sores, or small white specks in stool, parasites may be the underlying cause.
What to Do If Your Dog Is Licking Its Anus After Grooming
At home, first check the area for visible irritation, redness, or injury. Gently clean the area with a damp cloth to remove any potential residue from shampoos or sprays.
Switching to hypoallergenic, fragrance-free grooming products may prevent future irritation.
You can also offer a soothing balm recommended for canine skin, but avoid human creams unless directed by a vet.
If anxiety seems to be the trigger, comfort your dog with calm reassurance and positive reinforcement to reduce stress after grooming.
Make sure your dog is up to date on parasite prevention, as grooming may reveal signs of worms or fleas that contribute to licking. If anal gland issues are suspected, a vet should examine and empty them safely.
When to Call or Visit Your Vet
Persistent or severe licking after grooming should not be ignored. If you see swelling, bleeding, or a foul odor coming from the anus, it’s important to schedule a veterinary visit.
These can be signs of infection or abscesses that require medical treatment.
If your dog appears in pain, scoots frequently, or cannot stop licking, this also warrants veterinary care. Parasite infestations, allergic reactions, or injuries can worsen quickly if left untreated.
Finally, if at-home adjustments like switching products or cleaning the area don’t resolve the issue within a day or two, your vet can provide a more thorough evaluation and treatment plan.

Key Takeaway
When a dog keeps licking its anus after grooming, the cause may be as simple as skin irritation or as serious as an infection or anal gland issue.
Careful observation and at-home care may resolve mild cases, but persistent or severe symptoms require veterinary attention.
By responding quickly and compassionately, you can ensure your dog stays comfortable, healthy, and happy after every grooming session.
