Callus Pyoderma

What is Callus Pyoderma?
Some dogs tend to form calluses as result of lying on hard surfaces. Large breeds tend to form them on their elbows and hocks (ankles), whereas even some small breeds, such as Dachshunds, tend to form them on their chest.  Dobermans also tend to form chest calluses.  The calluses normally provide protection to these pressure points, but when they become infected the dog is said to have callus pyoderma.

How does my dog get Callus Pyoderma?
The calluses often contain small cysts around hair follicles, causing the remaining hairs to fall out. When the dog repeatedly presses down on the callused area it pushes this dislodged hair and accompanying debris, including bacteria, into the callus, where it sets up infected tracts.

How do I know if my dog has Callus Pyoderma?
Calluses are normally grayish in color. If they have reddened areas, bumps, blackheads, holes, or discharge, in part or whole, they are probably infected. Your veterinarian may be able to make a diagnosis simply by appearance, or may wish to take a biopsy for a more definitive diagnosis.

What can I do about Callus Pyoderma?
Your veterinarian will prescribe oral antibiotics, and may also prescribe medicated shampoo. You will need to keep the affected area from being further irritated, which means either keeping the dog on soft bedding, or affixing padding to the affected area.

Is there anything I can do to prevent my dog from getting Callus Pyoderma?
Because weight is a factor, so keeping your dog at a trim weight is helpful. Make sure he has access to soft bedding, and encourage him to use it. Carpet fibers may actually be somewhat abrasive, so blankets or padding is preferable to carpet.

Are there certain breeds that get Callus Pyoderma more often?
Large and giant breeds, or deep chested breeds that tend to lie on their chests, are predisposed.
