The onset usually occurred between 10 weeks and 1 year of age. First described by Paradis (1992), affected dogs exhibit a painful thickening of the footpads with severe keratinous proliferations and fissures only at the ground contact locations similar to those observed in FNEPPK patients . . . . Cracks predispose the dogs to secondary infections, leading to lameness, causing the dog to be reluctant to walk. Nails did not seem to be affected . . . Similarly, no other cutaneous sign such as oral leukoplakia, cysts, or follicular keratosis was reported. (Plassais et al, 2015)
