A. Licking of the feet is a sign of food allergies (especially the front feet). It is advised to start a limited ingredient diet (i.e. Evo (over the counter) or prescription Royal canin hypoallergenic hydrolyzed protein, Hill's Z/D) for a minimum of 2-3 months. Also if the nails are brown at the base, this is typical of a fungal infection and can be managed with anti-fungal fungal, which can be found at some petstores and at your local vet.
