Hyperkeratosis in Dogs

Have you ever stroked your dog’s nose and noticed that it is no longer smooth and normally moist, but rough, thickened or even crusty? Or perhaps you have noticed small hair-like growths on the paw pads that look as though someone has planted a miniature brush on them?

If so, it may be hyperkeratosis.

The word sounds complicated, but the idea itself is simple: hyperkeratosis means that the dog’s body is producing too much keratin. Keratin is a protein found in skin, hair, nails and paw pads. Normally, skin cells form, move towards the surface, die and shed. With hyperkeratosis, this balance is disrupted and keratin starts to accumulate where there should not be so much of it.

The result can be thick, dry, hard, cracked or crusty skin. It is most commonly seen on a dog’s nose, paw pads and sometimes the elbows.

The good news is that hyperkeratosis is usually not a reason to panic. The bad news is that if it is ignored, it can become uncomfortable or painful for the dog. As with many skin issues, noticing changes early matters.

What is hyperkeratosis?

Hyperkeratosis means excessive accumulation of keratin. When the skin functions normally, old skin cells are shed and new ones replace them. It is a little like a quiet cleaning crew working overnight without attracting much attention.

With hyperkeratosis, more keratin is produced than the body can remove. The skin becomes thicker, harder and drier. On the paw pads, small hair-like or feathery strands may appear. On the nose, the usual “cobblestone” texture can disappear and the surface may become dry, rough or crusty.

For some dogs this is mainly a cosmetic issue. For others it can cause cracks, bleeding, pain, lameness or a secondary bacterial or yeast infection. So hyperkeratosis does not automatically mean that something very serious is wrong, but it does mean that the dog’s nose and paws deserve attention.

Where does hyperkeratosis occur most often?

Hyperkeratosis is most commonly noticed on the paw pads, nose, elbows or other pressure points, and sometimes on both the nose and paws at the same time.

On the paw pads it may look like hard, dry, thickened skin. Sometimes hair-like keratin strands form around the edges of the pad. Changes on the nose may initially be very subtle: it may simply seem a little drier or rougher. Later it can become thicker, crusty and cracked.

My advice is simple: get into the habit of actually looking at your dog’s paws and nose, not only when the dog is limping or the nose is already damaged, but regularly. Paw pads are your dog’s tyres. The nose is the information centre. Both deserve a small technical inspection. Pay particular attention to the nose in spring when the sun is higher, because it can dry and crack more easily. Omega-3 oil and coconut oil can both be useful for moisturising the nose and paw pads.

What symptoms can indicate hyperkeratosis?

You may notice hard, thickened or dry skin on the paw pads; a rough or crusty nose; hair-like or feathery growths around the edges of the pads; loss of the nose’s normal pattern; cracks or fissures; bleeding; lameness or changes in gait; excessive paw licking; or redness, discharge, bad odour or crusting that may suggest a secondary infection.

If the change is mild and the dog shows no discomfort, there is usually no need to hit the panic button. But if the nose or paws are cracked, bleeding or painful, the dog is limping, licking the paws a lot or seems tired or generally unwell, it is worth contacting a veterinarian.

It is especially important not to start cutting, filing or picking away hard skin at home. If something needs to be removed, it should be done by a veterinarian. At home, it is easy to do more harm than good.

Why does hyperkeratosis develop?

Hyperkeratosis does not always have one clear cause. Sometimes it is age-related. In some cases it is associated with breed or genetics. It can also point towards a nutritional issue, infection or immune-system problem.

1. Age

In older dogs, the skin no longer renews itself as quickly as it did when they were young. They also often move less, which means the paws and nose may not wear naturally in the same way. If a dog moves less, lies down more and the paw pads receive less normal friction, keratin may begin to build up.

That is why with an older dog it is worth checking not only the eyes, teeth and joints, but also the paw pads. Sometimes a paw says more than the dog does.

2. Breed and genetics

Some breeds are more prone to hyperkeratosis. Breeds mentioned in the source material include Bulldogs, Boxers, Boston Terriers, Pugs, Cocker Spaniels, Basset Hounds, Beagles and Irish Terriers.

Labrador Retrievers can develop hereditary nasal parakeratosis, in which the nose becomes dry, rough or crusty at a young age. Dogue de Bordeaux dogs may develop familial footpad hyperkeratosis, which can appear even in puppyhood.

This does not mean that every dog of these breeds will develop hyperkeratosis. But if your dog belongs to a higher-risk breed, it makes sense to keep a closer eye on the nose and paws. Think of it as checking tyre pressure before a long drive.

3. Nutritional issues

Low levels of certain nutrients can affect skin health. The Bark & Whiskers article used as a source mentions zinc deficiency as one example because zinc can influence the regulation of keratinocytes, the skin cells that produce keratin.

Zinc-related skin problems are seen more often in breeds such as Siberian Huskies and Alaskan Malamutes, which may have inherited difficulties absorbing or using zinc. Rapidly growing puppies may also develop zinc-related problems if the diet is not balanced.

This does not mean that every dog with a dry nose needs a jar of zinc immediately. A supplement should not be the first blind throw in a dark kitchen. If you suspect a nutrient deficiency, talk to your veterinarian and review the dog’s whole diet.

From my own experience, even when a dog’s test values are within the reference range, that individual dog may simply need more of a particular nutrient than the standard recommendation suggests. For example, Oscar’s blood zinc level was nicely within range when he was a puppy, yet it was very likely that zinc was still part of the problem: his paw pads were pink and began to bleed easily. We resolved the problem by feeding nori sheets.

4. Infections

Some infections can affect keratin production. One example is canine distemper, sometimes called “hard pad disease” because it can cause hardening of the paw pads.

These situations are no longer simply a matter of dry paws. If a dog has general symptoms in addition to skin changes, such as lethargy, fever, loss of appetite, other skin lesions or generally feeling unwell, veterinary attention is essential.

5. Autoimmune diseases

Sometimes the immune system can begin attacking healthy skin cells. The body may then respond with excessive keratin production. Autoimmune skin diseases can cause hyperkeratosis on the nose or paws, but there are often other changes as well, such as redness, ulceration, crusting or skin problems elsewhere on the body.

These conditions cannot be “fixed” at home with coconut oil. A diagnosis is needed. Colostrum may, however, be used as supportive care in autoimmune conditions.

6. Repeated pressure or trauma

If a dog spends a lot of time lying on hard floors, thickened areas of skin may develop on the elbows or other pressure points. The body is trying to protect itself and produces more keratin there.

This is especially common in larger and older dogs that spend more time lying down. In this case, a simple soft bed can do more than yet another miracle jar from the kitchen cupboard.

When should you see a veterinarian?

A veterinarian should examine the dog if the paw pads or nose are cracked; there is bleeding; the dog is limping or avoiding walking; the dog licks or chews the paws; the area is red, inflamed, foul-smelling or has discharge; the dog is also tired, has poor appetite or other general symptoms; the change is getting worse quickly; the dog is young and belongs to a risk breed; or you suspect an autoimmune disease, infection or nutrient deficiency.

A veterinarian can assess whether this is simply mild hyperkeratosis or whether something else is behind it. If necessary, blood tests, skin tests, cytology, cultures or a biopsy may be used. That may sound intimidating, but the idea is simple: before treating the “crust”, we want to know why it appeared.

Can hyperkeratosis be cured?

Hyperkeratosis usually does not have a permanent “treat it once and it is gone” solution. If the cause is age or genetics, it is generally something that needs ongoing management. That is not necessarily bad news. Many dogs with hyperkeratosis live completely normal, happy lives when their nose and paw pads are cared for regularly.

Treatment or care depends on the cause and severity. Sometimes moisturising and monitoring are enough; sometimes a secondary bacterial or yeast infection needs treatment. In some cases, zinc deficiency, autoimmune disease, pain or another underlying cause needs to be addressed.

What can you do at home?

With mild hyperkeratosis, there is quite a lot you can do at home, within sensible limits. Home care does not mean taking scissors to the dog’s nose or pulling hard skin from the paw pads. It is much simpler than that.

1. Paw soaks

Soaking the paw pads in warm water may help. One of the source articles also mentions Epsom-salt paw baths, which may help soften the skin and reduce irritation.

Make sure the dog does not drink the water. Strong soaps are also best avoided because they can dry the pads even more. Dry the paws thoroughly afterwards. A damp paw inside a sock or on the carpet is not a gift to the skin, but a tiny spa party for yeast and bacteria.

2. Warm compress for the nose

If the nose is dry and rough, a warm damp cloth can be used. Hold it gently against the nose to soften and moisturise the skin, then apply a dog-safe moisturising balm if needed.

Do not block the nostrils. Dogs need their noses not only for sniffing, but also for breathing. It sounds obvious, but sometimes the most basic things are the easiest to forget.

3. Moisturising balms

Dog-safe nose and paw balms can help keep the skin more flexible and reduce the risk of cracking. Coconut oil and omega-3 oil are useful options, but both come with a small catch: dogs often believe that anything edible should be removed immediately. If your dog lets it stay on the nose or paw pads for even a minute, that is already helpful.

After applying something moisturising, try to keep the dog occupied for a little while. Go for a walk, offer an appropriate chew or simply supervise. Be cautious with shop-bought nose and paw balms and read the ingredients, because some products can upset digestion if the dog licks off a large amount.

For paw pads, a light bandage or sock may sometimes be used briefly to allow the balm to absorb, but it must not be tight and it needs to be removed at the right time.

4. Do not remove excess keratin yourself

If there is a lot of keratin and it is bothering the dog, a veterinarian can carefully soften and remove it. This can be uncomfortable and in some cases sedation may be needed. Do not attempt it at home unless your veterinarian has specifically shown you how.

A paw pad is not a piece of wood that can be sanded smooth.

5. A soft bed

If thickened skin develops on the elbows or other pressure points, look at where your dog sleeps. A hard floor, a thin mat and a heavy dog are a bad trio. A soft bed reduces repeated pressure and may help prevent the thickened areas from getting worse. This is particularly important for older and larger dogs.

Nutrition and skin: what can the food bowl support?

Skin is the body’s largest organ and often reflects what is happening inside. That does not mean every dry nose is caused by food. But a balanced, species-appropriate and well-digested diet is one of the foundations of healthy skin.

The Bark & Whiskers article notes that a balanced, species-appropriate diet, omega-3 fatty acids and, where relevant, ruling out nutrient deficiencies such as zinc-related problems may all be important in supporting the skin.

From FendaF’s perspective, this means three practical things.

1. Choose food that genuinely suits your dog

If your dog has sensitive digestion, recurring skin problems or suspected food intolerance, it may be worth choosing foods with a simpler, clearer ingredient list. Winner Plus foods available from FendaF, including monoprotein options, may suit dogs where the goal is to keep the composition understandable rather than turning the bowl into a patchwork. You can always add good-quality fruit and vegetables yourself.

For example, salmon-and-rice food or wet food with salmon can be useful options for dogs that tolerate fish and where omega fatty acids are desired to support the skin and coat.

This does not mean salmon food cures hyperkeratosis. It does not. But good nutrition can support the overall condition of the skin, and that is already significant.

2. Omega-3 may support the skin

Omega-3 fatty acids are among the most frequently discussed fats for supporting skin, coat and inflammatory processes. Bark & Whiskers also notes that food containing omega-3 fatty acids may support skin health and help reduce inflammation.

Winner Plus omega-3 salmon oil from FendaF can be a sensible addition for dogs that tolerate salmon oil, particularly if the diet does not contain enough marine omega-3 fatty acids.

But oils are not a “more is better” situation either. Oil is very calorie-dense and too much fat can be hard on digestion or the pancreas in some dogs. If your dog tends to gain weight, every extra calorie in the bowl also matters. Start slowly and watch your dog.

3. Natural treats, not sugary biscuits

If your dog has skin issues, it is worth reviewing the treats too. Dr Judy Morgan points out that owners often improve the main diet while continuing to give daily treats with an ingredient list that resembles a small chemistry laboratory, and then wonder why the skin is still protesting.

FendaF’s natural treats are a logical option because they do not need added colours, aromas, flavours or preservatives to make dogs want them. To a dog, a real smell and a real ingredient matter much more than a biscuit shaped or scented to appeal to humans.

When the skin is already signalling a problem, a treat can be as simple as possible: one animal source, a clear composition and a sensible amount. No sugar hat and no mysterious “flavour blend”.

A small practical checklist

If you notice thickened, dry or crusty skin on your dog’s nose or paw pads: check where the change is located; see whether the skin is merely dry or already cracked, painful, red, bleeding or producing discharge; watch for limping, paw licking or reluctance to walk; do not cut or file excess keratin yourself; for mild changes, try gentle moisturising, a paw soak or a warm compress; check the sleeping area, especially if the thickening is on the elbows; review whether the diet is balanced, suitable and well tolerated; review treats and supplements; consult a veterinarian if the dog is young, belongs to a risk breed or the change is progressing quickly; and seek veterinary care if there is pain, bleeding, lameness, bad odour, discharge or general illness.

What should you definitely not do?

Do not cut away hard skin yourself, use strong human creams without discussing them with a veterinarian, apply anything so thickly to the nose that it blocks the nostrils, let the dog immediately lick off the entire balm, ignore lameness or bleeding cracks, or assume that “it is just an old-dog thing” automatically means that nothing can be done.

Age may be a reason, but it does not have to be an excuse.

In summary

Hyperkeratosis is usually not life-threatening, but it can affect a dog’s comfort. The nose and paw pads are not merely cute details. They are your dog’s tools. A dog experiences the world through the nose and moves through life on the paws.

If the nose becomes rough or the paw pads start to thicken, do not panic, but do not ignore it either. Look, touch, monitor and ask for advice when needed. With mild hyperkeratosis, regular care can do a lot: moisturising, a soft bed, paw checks, a balanced diet, omega-3 support and simple natural treats.

And as always, do not treat only the “crust”. Look at the whole picture. A dog’s skin often whispers before it starts to shout.
