CRACKED FOOT PADS IN DOGS
There are several known causes of cracked foot pads and unfortunately unknown
reasons of this disorder. If a dog chews its paws, it may be walking in or
on a chemical that’s irritating its feet. Rug shampoos, floor cleaners, or
garden sprays, for example, can irritate the paws of some dogs. The sore
and inflamed paws that result may prompt the animal to chew its feet, aggravating
the existing irritation and causing pad cracking. Some other possibilities
are that the dog may be having an allergic reaction to a substance it breathes
or eats, a chronic yeast infection similar to athletes foot, a nutritional
zinc deficiency, or autoimmune disease. A veterinarian can help identify
possible culprits and suggest ways to eliminate the problem.
Yeast infections may be diagnosed by the evaluation of skin smears taken
of the paw. This condition is treated by the use of antifungal medications.
Zinc deficiencies may be diagnosed through history, clinical signs, skin
biopsy, breed predisposition, diet, and age. In rapidly growing dogs, either
feeding a diet high in cereal or calcium may produce this disease. Breeds
reported to have this disease are Great Danes, Dobermans, Beagles, Shepherds,
German Short Haired Pointers, and Poodles. Certain breeds such as the Husky
or Malamute may have a decreased absorption of zinc through the digestive
Allergy testing through a blood sample or skin testing is also available
to assist us in treating your pet. Your veterinarian will then recommend
if indicated allergy injections to stimulate your pet’s immune system.
Another possibility is nasodigital hyperkeratosis - an ailment affecting
either the nose or foot pads (or both) of older dogs. In hyperkeratosis,
keratin - the tough, fibrous outer covering of foot pads - grows excessively.
Often, the hard, cracked pads appear to have "keratin feathers" around their
edges. A vet can diagnose this ailment by analyzing a section of pad tissue.
Although hyperkeratosis can’t be cured, it can be controlled. The veterinarian
can carefully trim excessive keratin and instruct the owner on techniques
to hydrate the pads, retarding excessive keratin growth. One such technique
is to soak the pads each day in a 50 percent propylene-glycol solution over
a period of several days.
Lastly, an animal can suffer from an auto-immune disease of the skin (pemphigus),
in which the immune system goes haywire and mistakes skin cells for enemy
invaders. In the most common type of pemphigus, pus-filled sores - which
eventually break and form crusts - develop on the foot pads, bridge of the
nose, and ears. Again, a vet can test for pemphigus by analyzing a sample
of the affected skin. If pemphigus is the culprit, the veterinarian may treat
it with immune-suppressing drugs.
