Hyperkeratosis is a nasal planum disease caused by an overgrowth of skin cells (keratin) on the surface of a dog’s nose. Vets often refer to canine hyperkeratosis as idiopathic in nature, meaning we don’t always know exactly what causes it.
If your dog has nose hyperkeratosis, you may notice the skin on top of their nose looks rough, thick, and even crusty or cracked due to this excess keratin.
These signs of hyperkeratosis aren’t usually a cause for concern. But they shouldn’t be ignored either. If left untreated, or if underlying causes aren’t addressed, a mild case of nasal hyperkeratosis can become severe, leading to a lot of discomfort and even infections.
👉 Always watch out for signs of secondary infection, like blood, odor, or mucus-like discharge. If these symptoms appear, have your dog checked out by your veterinarian immediately.
Nasal hyperkeratosis is more than just a dry dog’s nose or itchy skin; it’s really a buildup of an additional growth of skin. Canine hyperkeratosis is a much more pronounced dry nose, usually marked by thicker skin on top of the snout. There can be many possible underlying cause factors to consider.
Some dogs that have nasal hyperkeratosis also suffer from paw pad hyperkeratosis at the same time. Also known as footpad hyperkeratosis, this condition affects a dog’s paw pads. Not every dog with one condition will have both, though.
Oftentimes, when dogs develop an overgrowth of skin cells on their paws, it’s due to gait abnormalities. On the other hand, not much is known about why nasal hyperkeratosis develops in dogs.
Certain dog breeds are genetically predisposed (Trusted Source) to developing hyperkeratosis. These include brachycephalic breeds, those ‘smoosh-faced’ breeds, such as English Bulldogs, French Bulldogs, Pugs, and Boxers, as well as Doberman Pinschers, and Cocker Spaniels. Occasionally, English Cream Golden Retrievers can even get it. It’s also more common in middle-aged to older dogs.
Certain external and environmental factors can also cause canine hyperkeratosis. A few examples include:
When determining if your dog has nasal hyperkeratosis, it is important to have your pup evaluated by your vet to rule out other conditions or underlying causes that can sometimes show similar signs.
Because these underlying conditions could cause signs similar to nasal hyperkeratosis, it is always a good idea to have your pup checked out by your vet to be on the safe side. Some of these conditions can be life-threatening, so finding the cause is important. In addition to biopsies and blood work, pet owners should expect other diagnostic tests to help identify the cause.
While the symptoms of nasal hyperkeratosis in dogs can be treated, in some cases there isn’t a cure. It’s important to note that you will likely need to follow a management plan for the remainder of your dog’s life.
Management includes rehydrating and moisturizing your dog’s skin with warm water soaks and applying a soothing ointment on a daily basis. Nose balms and other vet-recommended therapies (such as Vaseline) can be helpful here.
There are also pet-specific natural balms available for this purpose. Or, you can make your own DIY nose balm.
👉 Avoid putting hydrogen peroxide, rubbing alcohol, Neosporin, baby oil, or any topical human medications on your dog’s nose.
While many people look to CBD oil as a remedy for many of their pet’s medical conditions, CBD oil does not do much for nasal hyperkeratosis. Coconut oil is fine to apply to the top of your puppy’s nose, although Vaseline and the available nasal balms are typically thicker, and provide a longer-lasting and more soothing effect.
Before starting any kind of at-home treatment, it’s important to first speak to your vet. Finding out the cause of your dog’s nasal hyperkeratosis will help you narrow down effective treatments for long-lasting results. Once you know the cause, eliminate your dog’s discomfort with soothing balms that will also reduce the likelihood of infection.
Lastly, monitor them closely—make sure that they are healing infection-free, that their appetite stays normal, and that they are comfortable.
Common causes include autoimmune diseases and certain skin infections. For some dogs, dead and old skin cells simply aren’t rubbed off in their day-to-day activities. Unfortunately, nasal hyperkeratosis is one of many conditions that sometimes doesn’t have a “known” cause.
Getting rid of hyperkeratosis on a dog’s nose depends entirely on the cause. Sometimes a dog’s nose can just get dry and cracked due to things like winter wind. Sometimes, it’s nasal hyperkeratosis, which can be caused by a number of other factors ranging from genetics to diseases caused by various external factors.
While proactive care may stop any flare ups of nasal hyperkeratosis, depending on the cause and severity, it may be a condition that has to be managed for the rest of your dog’s life. If the cause is a fungal infection, as an example, simply limiting exposure may prevent nasal hyperkeratosis.
Nasal hyperkeratosis can be uncomfortable for your pet, which is why intervention is so important. Your vet can help by offering balms and other supportive therapies that can reduce the symptoms and help support one’s quality of life.
Yes, there are breeds that may be genetically predisposed to hyperkeratosis. Some of these breeds include Brussels Griffons, Doberman Pinschers, Cocker Spaniels, to name a few.
