My English bulldog was treated for every type of skin irritation in the book. She frequently had infections that required medication-sprays, pills, special shampoo-on and on. One fortunate day for Daisy and me, we saw a new vet in the practice. He suggested we try to approach her skin condition as a food allergy. We changed her food and she has not had any more problems. She eats Iams for sensitive skin and looks wonderful. No more constant itching and scratching. I hope you find your solution. We were just very lucky.
