Many dog owners notice a rough, gray, hairless patch on their dog’s elbows and wonder whether it is a problem. In most cases these patches are calluses, thickened skin that forms in response to pressure. They are common, especially in big dogs, and usually harmless on their own. They can crack, get infected, or turn into pressure sores, so it is worth knowing what to watch for.
This is general information. A vet should look at any skin change that is new, painful, or changing.
What is a dog callus?
A callus is an area of thickened, hardened skin that develops where the body repeatedly presses against a hard surface. The skin builds up a tougher layer for protection. Elbows are the most common place, but calluses can also form on the hocks (the ankle-like joint of the back leg), hips, and the chest bone (sternum).
Why dogs get calluses
Calluses usually come from repeated pressure and friction. Contributing factors include:
- Hard surfaces. Lying on tile, concrete, hardwood, or the ground often.
- Large or heavy body size. Bigger and heavier dogs put more weight on their joints. Large and giant breeds are commonly affected.
- Body weight and shape. Short coats, thin skin over bony points, and excess weight can all play a part.
- Age and mobility. Older dogs or dogs with arthritis may flop down heavily or lie in awkward positions.
- Lack of soft bedding. Dogs often choose cool, hard floors in warm weather, so a soft bed may go unused.
So yes, dogs do build up calluses, and they often become more noticeable as dogs age.
What does a dog callus look like?
Typical features include:
- Thick, rough, or wrinkled skin
- Gray, dark, or pink color
- Hair that is thin or absent
- A flat or slightly raised patch over a bony joint
- Usually no pain
A callus that is a different color, bleeds, looks ulcerated, or grows quickly needs a vet exam. A soft, fluid-filled swelling at the elbow can be a different problem, called a hygroma, and a vet should check it.
Do calluses go away?
Sometimes they improve when the pressure is reduced and the skin gets a chance to recover, but they may not disappear completely. Hair may not grow back, and the thickened skin often lingers. The goal is mostly to keep the area comfortable, soft, and free of cracks or infection rather than to erase it.
Treatment and home care
Most care centers on reducing pressure and keeping the skin healthy.
- Offer soft, supportive bedding. Thick, cushioned beds or orthopedic mats give your dog a more comfortable alternative to hard floors. Place bedding where your dog likes to rest, and consider a cooling mat in warm weather, since dogs may choose cold floors to stay cool.
- Add padding on slick or hard surfaces. Rugs or mats in favorite resting spots help.
- Use protective gear if needed. Elbow pads or sleeves are sold for dogs. Fit matters. If they rub or cause sores, stop using them and ask your vet.
- Moisturize carefully. Dog-safe balms may soften dry or cracked calluses. Ask your vet which products are appropriate, and avoid anything with ingredients that could harm a dog who licks it. Offering a treat or a short walk after applying a balm may keep your dog from licking it off right away.
- Keep the area clean and dry. Gently wipe away dirt with a damp cloth.
- Manage weight and joint health. If your dog is overweight or has trouble getting up and lying down, discuss ways to help with your vet.
- Watch the skin regularly. Check for cracks, redness, or sores.

Can I remove a callus?
Please do not cut, scrape, or file a callus, or use acids or harsh products on it. Doing so can cause bleeding, pain, and infection. Calluses are protective tissue. If a callus is cracked, very thick, or bothering your dog, ask a vet about safe options.
What does an infected callus look like?
Infection or complications may show up as:
- Redness around the area
- Swelling or warmth
- Open sores, cracks, or bleeding
- Pus, discharge, or crust
- A bad smell
- Pain, flinching when touched, or constant licking
- Hair loss spreading beyond the area
- A fluid-filled bump that grows
If you see any of these, schedule a veterinary visit. Prompt treatment prevents small problems from becoming larger ones, particularly because pressure sores can be slow to heal.
When to see a vet
Contact your vet if:
- The patch is new and you are unsure what it is
- It is red, raw, bleeding, smelly, or oozing
- Your dog is limping, licking at it, or in pain
- A lump or swelling appears or changes in size
- The skin keeps cracking
- You suspect arthritis, since pain management and mobility help reduce pressure sores
A vet can also rule out other skin conditions, including infections and growths that can resemble calluses.
Prevention
- Provide comfortable beds in multiple rooms
- Encourage your dog to rest on soft surfaces
- Keep your dog at a healthy weight
- Provide cooling options that are not hard flooring
- Support older dogs with traction and mobility help
- Check elbows and other pressure points as part of regular grooming
FAQs
Do calluses on dogs go away?
They can improve with less pressure, but they often do not vanish entirely and hair may not regrow.
How do I remove calluses from my dog’s feet?
Do not scrape or cut them. For paw pads that look thick or cracked, see your vet. For paw irritation more generally, see our guide to dog licking paws.
What does an infected callus look like on a dog?
Redness, swelling, pus, a bad smell, open sores, or pain are warning signs. See a vet if you notice them.
Do dogs build up calluses?
Yes. Repeated pressure on hard surfaces can cause thickened skin, especially in large or older dogs.
