What it is
The paw pads are covered by a thick, tough layer of skin built from keratin, the same protein that makes up the claws. In this disorder an inherited fault makes the pad skin produce keratin far faster than it wears away. Hard, horn-like growths pile up on the surface, and the pads lose the springiness that cushions every step.
The changes appear while the dog is still a puppy, within its first months, and affect the pads on every paw. Thickened pads are less supple, so they crack, and the cracks can hurt, collect dirt and become infected.
Day to day, a dog with sore pads may be less keen on long walks, especially on hard or hot ground, and may pick softer spots to lie on at home. Checking the paws after walks helps you spot new cracks sooner.
Signs you may notice
- Thick, hard paw pads
- Horny growths on the pads
- Cracked pads
- Limps or walks gingerly
- Keeps licking its paws
- Avoids hard ground
The changes show up while the dog is still a puppy: the pads look thick and rough, with horny growths or cracks. The dog may limp, avoid hard ground or lick its paws a lot.
When to see a vet
Book a vet visit if a puppy's pads look abnormally thick or cracked, or your dog starts to limp. Go sooner if a crack bleeds, swells or smells bad, as it may be infected.
