If you've noticed your dog's paw pads looking thick, crusty, or even slightly hairy around the edges, you may be seeing hyperkeratosis, sometimes called "hairy paw" or "hairy feet." It's a condition where the body produces excess keratin, the protein that makes up paw pads, nails, and skin, causing the pads to grow thick, dry, fringed layers. While it often looks worse than it is, understanding what you're seeing helps you care for your dog's paws properly and know when a vet visit is warranted.
What Hyperkeratosis Looks Like
The hallmark sign is a thickened, crusty layer on the paw pads that can look like dried, cracked skin or fine hair-like fringes growing from the pad edges. The pads may feel rough and dry rather than smooth and supple. In some dogs, the nose is affected too, appearing dry and crusty. It most commonly shows up in older dogs and in certain breeds, including Labradors, Golden Retrievers, and various terriers, though any dog can develop it.
It's important to distinguish hyperkeratosis from simple dryness. Dry pads from winter weather or rough terrain usually improve with moisturizing and rest. Hyperkeratosis is a persistent overgrowth of keratin that doesn't resolve on its own, though it can often be managed comfortably at home.
What May Contribute to It
Hyperkeratosis can be part of the normal ageing process, a breed predisposition, or occasionally associated with underlying health conditions such as autoimmune disorders or, rarely, more serious illnesses. That's why a first diagnosis should come from your veterinarian, who can rule out other causes and confirm what you're dealing with. Never try to cut or peel the excess keratin yourself; the tissue underneath is sensitive and can bleed or become infected.
Home Care for Affected Paws
- Keep pads moisturized. Regular application of a pet-safe, lick-safe paw balm softens the thickened keratin, keeping it flexible and reducing the risk of cracking and splitting.
- Soak before softening. A brief soak in warm water before applying balm helps moisture penetrate the thickened tissue.
- Protect from extremes. Dogs with hyperkeratosis are more vulnerable to rough, hot, or frozen surfaces, so consider booties or balm before walks in harsh conditions.
- Watch for cracks and limping. If the thickened pads crack deeply, bleed, or your dog starts limping or licking excessively, see your veterinarian. Your vet may need to carefully trim the excess keratin in the clinic.
- Keep up with regular vet checkups. Since hyperkeratosis can occasionally signal an underlying condition, ongoing veterinary monitoring is sensible, especially if it appears suddenly in a younger dog.
Hyperkeratosis vs. Everyday Dryness
Not every rough paw pad is hyperkeratosis. Normal seasonal dryness feels slightly rough but looks relatively smooth, and it improves within a week or two of regular moisturizing and reduced exposure to harsh surfaces. Hyperkeratosis, by contrast, produces visibly thickened, layered, or fringed tissue that persists despite moisturizing. Another lookalike is a healing injury: a pad recovering from a cut can look thick and uneven for a few weeks. If you're unsure which you're seeing, your veterinarian can tell the difference at a glance during a routine visit.
When Home Care Isn't Enough
Moisturizing manages hyperkeratosis but doesn't reverse it. Book a veterinary visit if the thickened tissue cracks deeply, bleeds, or develops sores; if your dog limps, licks the paws obsessively, or seems in pain; or if the condition appears suddenly in a young dog, which is less typical and worth investigating. In the clinic, a vet can safely trim back excess keratin and check for underlying conditions contributing to the problem.
Key Takeaways
- Hyperkeratosis causes thick, crusty, sometimes hair-like overgrowth on paw pads (and sometimes the nose).
- It's common in senior dogs and certain breeds, and should be confirmed by a veterinarian.
- Never cut or peel the excess tissue at home.
- Regular moisturizing with a lick-safe paw balm keeps affected pads comfortable and reduces cracking.
