A lick granuloma, also known as acral lick dermatitis, is a skin condition that affects dogs. It happens when a dog constantly licks one area, usually on the leg, until the skin becomes irritated, inflamed, and eventually thickened. If left untreated, it can lead to infection and ongoing discomfort for your dog.
What Causes a Lick Granuloma?
Dogs develop lick granulomas for several reasons, including:
- Boredom or Anxiety – Some dogs lick out of stress, separation anxiety, or lack of mental stimulation.
- Pain or Discomfort – Arthritis, joint pain, or an injury might make a dog focus on licking a particular area.
- Allergies – Skin irritation from food allergies, environmental triggers, or flea bites can cause excessive licking.
- Infections or Parasites – Bacterial or fungal infections and parasites like mites can trigger itching and licking.
- Neurological Issues – Some dogs develop compulsive licking as a behavioural issue, similar to obsessive-compulsive disorder in humans.
Symptoms of a Lick Granuloma
A lick granuloma usually appears as:
- A red, inflamed patch of skin
- Thickened, hairless skin in the affected area
- Ulceration or open wounds
- Signs of pain or sensitivity when touched
- Continued licking or chewing of the same spot

Treatment Options
Treating a lick granuloma can take time, as the condition often becomes a habit for the dog. Addressing the underlying cause is key.
Veterinary Treatment
If the granuloma is severe, a vet may recommend:
- Medications – Antibiotics or antifungal treatments if infection is present.
- Anti-inflammatory drugs – Steroids or other medications to reduce swelling and irritation.
- Pain Relief – If arthritis or joint pain is causing the licking, pain medication may help.
- Elizabethan Collar (E-collar) – To prevent licking and allow the area to heal.
- Laser Therapy – Some vets offer laser treatments to speed up healing.
Home Treatment and Management
For mild cases, or alongside vet treatment, you can try these home remedies:
- Bitter Spray or Bandages – Spraying a bitter-tasting deterrent or covering the area with a breathable bandage can discourage licking.
- Keep Your Dog Busy – Provide mental and physical stimulation, like puzzle toys, chew toys, and longer walks to prevent boredom.
- Address Anxiety – If stress is a trigger, calming supplements, a consistent routine, and interactive play can help.
- Topical Treatments – Natural remedies like aloe vera, coconut oil, or diluted apple cider vinegar may soothe irritation (always check with your vet before applying anything new).
- Improve Skin Health – Omega-3 supplements or a balanced diet can help support healthy skin and reduce inflammation.
When to See a Vet
If your dog’s lick granuloma is getting worse, has open sores, or isn’t improving with home care, it’s best to see a vet. The sooner you address the issue, the easier it will be to break the licking cycle and help your dog heal.
Final Thoughts
Lick granulomas can be frustrating to deal with, but with patience and the right approach, you can help your dog recover. Finding the root cause, whether it’s boredom, pain, or an allergy is essential to stopping the habit. If home treatments aren’t working, don’t hesitate to get professional advice. Your dog’s comfort and well-being are worth it!
