I am in the process of finishing up the kibble I have on hand, in order to switch my boys over to raw, in about a week now. There are tons of websites dedicated to raw feeding. They vary from advocating meat, bones, veggies, fruits and a dozen different supplements all together or in varying combinations. Read through some of them and then make your decision on what is right for you and your dogs, with input from your vet, if you trust them. Max and Cody have severe allergies, Jake has recurring ear infections. I am hoping that the new diet will at least help with some of this, but even if it doesn't, I truly believe it will be better for them. Look at the bag of food, if you have it, or go online and compare the ingredients in what you were feeding to what you are feeding now. You should be able to spot some ingredient differences. It is very possible that there is something in the new food that she is allergic to. Lots of dogs are allergic to soy, dairy, beef, chicken, wheat, corn, etc. This should help in determining what caused the problem. By changing to a food that doesn't have whatever the ingredient is, it should clear up. You can also search online for the dog food you want to feed them and then search for retailers or online distributors. Amazon.com and a ton of other websites sell dog food. Good luck in your decision on either buying online or changing over to raw.
