It offer a barrier between the body and the remainder of the humans , ensuring that moisture is kept in and harmful element , like ultraviolet radiation and bacteria , are keep out . Keratin protects and beef up cell and aid prevent cell death and damage
Keratinocytes
Keratinocytes are the cell in the cuticle that make keratin . Within the cuticle , layers of keratinocytes undergo a uninterrupted operation of growth , maturation , and expiry so that enough keratin is always present in the tegument . When these cubicle buy the farm , they slough off along with other cadre that make up the skin . Keratin is crucial for the constitution of nails , horn , hooves , hair’s-breadth , beaks , and claws , but when something goes wrong with the life cycle of keratinocytes , it can become a job for the fauna .
Symptoms of Hyperkeratosis in Dogs

Hyperkeratosis has a typical appearance of thickset frond - like or feather pelt giantism in areas like the top of the olfactory organ , mitt inking pad , and elbow .

Trauma
When an arena of the skin is repeatedly traumatized , the keratinocytes may respond by overproducing ceratin . This can be seen in cases of hyperkeratosis at pressure points . For representative , if a wiener is often lie down on a heavy level without adequate bedding and develops pressing sores on the elbows , hyperkeratosis may evidence in the affected areas .
Systemic Disease
Hyperkeratosis can also occur from systemic infections likecanine distemper virusand leishmaniosis , a protozoal contagion fan out by bite flies . Immune - mediated disease , like systemic lupus erythematosus and pemphigus foliaceus , can also get hyperkeratosis .

Other condition such asleishmaniasisandcanine distemper virushave a poor prognosis and treatment depends on the disease and how disgusted the ducky is , and may run from hospitalization to even humane euthanasia in some cases .

For dogs with ancestral and idiopathic hyperkeratosis of the nose and infantry pads , the medical prognosis is good . Even though the condition ca n’t be cured , it can be managed so that andiron are well-situated and have minimal symptoms .
For dogs with underlying diseases , the prospect browse from effective , as in the causa of zinc - reactive dermatosis if the deficiency is reversed , to hapless for infection like leishmaniasis and distemper . wienerwurst with systemic diseases will most likely require lifelong medications and on-going management .
