I'm sure this has been discussed before. Gracie's breeder and my vet said it was okay to switch Gracie to adult food soon since she is thriving. She is presently on Iams Active Smart Puppy. My vet said Gracie's coat wasn't as shiny as it should be. She made a recommendation on some adult foods that included Merrick, Innova, Solid Gold and Nature's Variety. My other dog I use to have had been on Solid Gold for years and did okay with it. I worry about the food after what happened last year with some of the dog's dying. I want her to be on something natural that will help with her coat and general health. What do you all use here?
