Charlotte has been eating Purina One Smartblend for over a year now... she has also had skin/allergy issues for over a year now and we have tried everything. We talked to a new vet yesterday to get a second opinion and she suggested starting her on a restricted diet. She didn't go into much detail on that because she was really pushing getting allergy testing done, but with the initial visit to the dermatologist costing $600 that is not within reach for us right now. So I want to try and change what we are feeding her and was thinking of going with grain-free. Can anyone recommend something that would be readily available that we could try (something not incredibly expensive either)? Thanks guys!
