Hereditary footpad hyperkeratosis is a hereditary autosomal recessive disease found in dogs and humans. It is well described in Dogue de Bordeaux. The symptoms appear at 4–5 months of age and include a painful thickening and hardening of the footpads with severe keratinous proliferations and fissures, leading to development of cracks. Those cracks predispose affected dogs to secondary infection, which leads to lameness.
