A friend introduced me to NutVet Plus. My little dog was pulling out the hair by the roots on both back legs. Within a few days after using the product she stopped doing it. Now about 3 months later the hair has all grown back nice & thick. So pleased with the product & plan to start my other dog on it also. Have this set upon auto shipment. So pleased with the product & plan to use it for the life for both my little dogs.
