My staffy dog had this for years, changed his diet to raw and never been bothered since, tried all the vet stuff steroids tablets etc, acv in water helped as well as diluted spray on his paws, done allergie tests, cereals in dog food were the culprit, dogs arnt designed to eat cereals and grains, I'm actually cheaper feeding him raw food than commercial dog foods. I buy it frozen and delivered to the door. Never been healthier
