Nasodigitic hyperkeratosis in dogs may be idiopathic, secondary to an underlying disease, or due to congenital abnormalities in the normal anatomy of the nose and fingertips. In the case of congenital anatomical abnormalities, contact between the affected area and rubbing surfaces is impaired.
Pemphigus foliaceus is the most common autoimmune disease of the dog. [1] Blisters in the epidermis rapidly break to form crusts and erosions, most often affecting the face and ears initially, but in some cases spreading to include the whole body. The paw pads can be affected, causing marked hyperkeratosis (thickening of the pads with scale).

Though it can also be found in other places like the lower lip, nose, elbow, pre-patellar region, and periungual tissue, it mostly affects the fingers and toes. [6] Usually, the lesion is smaller than 1 cm, however reports of acral fibrokeratomas larger than 1 cm, known as giant acral fibrokeratomas, have been made.
The dermis is the layer of skin between the epidermis and subcutaneous tissue, and comprises two sections, the papillary dermis and the reticular dermis. [10] The superficial papillary dermis interdigitates with the overlying rete ridges of the epidermis, between which the two layers interact through the basement membrane zone. [ 10 ]
Type 3: Focal acral hyperkeratosis (also known as "Acrokeratoelastoidosis lichenoides", and "Degenerative collagenous plaques of the hand") is a late-onset keratoderma, inherited as an autosomal dominant condition, characterized by oval or polygonal crateriform papules developing along the border of the hands, feet, and wrists.
Keratosis pilaris (KP; also follicular keratosis, lichen pilaris, or colloquially chicken skin. [1]) is a common, autosomal-dominant, genetic condition of the skin's hair follicles characterized by the appearance of possibly itchy, small, gooseflesh-like bumps, with varying degrees of reddening or inflammation.
