A dogâ€™s paws are the equivalent of human hands and feet. The skin of the digital pads is thick and pigmented. The roughness of the surface is due to conical papillae-multiple small protuberances – which may become rounded if the dog is exercised regularly on concrete or rough ground.
The pads of the feet can sometimes become cracked through a lot of activity on rough ground, and they can be cut by sharp objects. Such injuries may cause lameness.
Applying Vaseline to the pads twice a day may help to make them suppler and less cracked and washing and drying the paws after walks may remove allergens and reduce any allergic disease.
Should the paws not settle down consult a vet, it could well be a dietary insufficiency.
