Abstract
Idiopathic nasodigital hyperkeratosis (INH) is a visually distinctive disorder in dogs with a typical history and that are otherwise healthy. INH was diagnosed in 35 dogs, accounting for 0.4% of the canine dermatology cases and 0.1% of the canine hospital population over an 11-year period. English bulldogs, miniature poodles, miniature schnauzers, American cocker spaniels, and Doberman pinschers may be predisposed. Most dogs (71.4%) had only nasal involvement. The condition is usually asymptomatic, stable over time, and not reported to spontaneously resolve.
