Dog Paw Pads Cracked? Causes, Care and When to See a Vet

Why paw pads crack in the cold months

A paw pad is thick, tough skin, but it is still skin. It dries out, wears down and splits the same way the skin on your heels does, and winter stacks several causes together.

• Dry air, inside and out. The AKC names both the dry air in your home and the cold air outside. Heated rooms in January are part of the problem, not just the walk.
• Salt, de-icers and ice. Cornell says paws can get cracks or cuts from ice and salt on the roads, and that road salt and de-icers can irritate paws. The ASPCA’s cold-weather tips say cold, dry winter air can cause chapped paws and itchy, flaking skin, and that clinging ice balls, salt crystals and de-icing chemicals can dry the skin further.
• Hard, rough ground. Long walks on pavement wear pads down in any season. The AKC’s article on hyperkeratosis mentions cracked, hardened pads in dogs that walk a lot on pavement or hot surfaces, and VCA’s first-aid page warns against hot sidewalks in summer and icy or salt-covered sidewalks in winter.
• Wet, then dry, then wet again. Slush on the walk, a warm floor at home, then the next walk. Our guide to what ice melt does to paws covers the chemical side of this in more detail.

If your dog’s pads started cracking in late fall and the dog walks city sidewalks, this list probably explains it. If the cracking started in summer, affects a dog who mostly walks on grass, or keeps getting worse despite care, read the next section.

When cracking is a sign of something else

Some pads crack because the skin is making too much keratin, the protein in skin, hair and nails. The AKC’s hyperkeratosis article, which quotes a veterinarian, describes it as overproduction of keratin that most often shows on the paw pads or the nose, and calls it a clue about a dog’s health rather than a diagnosis in itself. It links it to aging, to zinc problems (it notes Siberian Huskies and Alaskan Malamutes are predisposed to zinc deficiencies) and to various autoimmune diseases.

The Merck Veterinary Manual adds the veterinary view. It describes an inherited form, familial footpad hyperkeratosis, reported in Irish Terriers and Dogues de Bordeaux, where all the pads are involved from a young age. When it is severe, it says, horn-like growths, fissures and secondary infection cause pain and lameness. It also lists the conditions a vet would want to rule out when pads thicken, including a liver-related skin syndrome and pemphigus, an autoimmune skin disease.

You don’t need to remember those names. What matters is the pattern that should send you to the vet instead of the balm tin.

What helps with ordinary dry, cracked pads

This is the routine for the first row of the table: dry pads, no bleeding, a dog that walks normally. It is care, not treatment, and if anything on the paw looks like a wound, skip straight to your vet.

• Get the salt off every time. The ASPCA says to wash and dry your dog’s feet and stomach after each walk to remove ice, salt and chemicals, and Cornell says to wipe or wash paws after returning inside. A bowl of lukewarm water by the door is enough.
• Dry between the toes, not just the top. Damp skin between the pads is where small cracks turn sore. The AKC suggests gently parting the toes as you clean to check for debris and irritation.
• Use a balm made for paws. The AKC suggests a soothing paw balm or protective paw wax, and the ASPCA says to massage petroleum jelly or other vet-approved paw protectants into the pads before going outside. If you’re unsure what to use, ask your vet. Dogs lick their feet, so whatever goes on will partly end up in the mouth.
• Don’t cut or peel rough skin. The AKC’s hyperkeratosis article is direct: don’t aggressively peel or cut thickened tissue at home, because over-trimming can cause pain, bleeding and infection.
• Change the route before you change the gear. Grass and packed snow are easier on pads than salted sidewalks. Shorter walks on the worst days help too.
• Look at the pads once a week in good light. The ASPCA says to check for cracks in the paw pads or redness between the toes. A phone photo makes it easy to compare.

If the cracks don’t settle within a couple of weeks of this, or they get deeper, treat that as a reason to see the vet, not a reason to try a stronger product.

Do boots help cracked paw pads?

For prevention, often yes. The AKC calls dog booties one of the easiest ways to protect paws from the elements, the ASPCA says booties give more coverage and keep sand and salt from getting lodged between bare toes, and Cornell suggests training your dog to wear well-fitting booties. On a salted city route, a boot keeps the main cause of winter cracking off the pad entirely.

Two honest caveats. A boot that doesn’t fit rubs, and a rub on an already cracked pad makes things worse, so fit matters more here than usual. Our guide on why dog boots keep falling off covers sizing from a standing paw. And boots are not a treatment for a crack that is open or bleeding. If your vet has looked at it and wants it covered, follow their instructions on how and for how long.

Not every dog needs boots for this. A dog that walks on grass and gets a thorough wipe at the door may do fine with balm alone. Our page on whether dogs need boots in winter goes through which dogs benefit most.

When to call the vet

The VCA first-aid page sets the clearest lines. It recommends a vet visit even for minor foot pad injuries because they can be stubborn, and notes that pads don’t hold stitches well, so cuts heal slowly. Call your vet, or go to an emergency clinic where VCA says to, if you see any of these:

• Bleeding that won’t stop after 10–15 minutes of pressure. VCA calls that an emergency.
• A crack or wound that keeps bleeding or gapes open after three days.
• Swollen toes, a foul smell or moist discharge, which VCA says can mean infection or poor circulation.
• Limping, or your dog refusing to put weight on the foot.
• Licking or chewing the paw that won’t stop.
• Thick, crusty, horn-like pads, especially with changes on the nose or elsewhere on the skin.

Bring the details a vet will ask about: when it started, which feet, where you walk, any de-icer you use at home, diet changes, and anything you’ve already put on the paw.
