Just a note of caution to anyone looking at dog foods, especially grain-free varieties. My vet's nutritionist told me that new research indicates that the main culprit in the heart issues recently discovered is the use of potatoes, peas and pea products in grain-free foods as a substitute for rice, barley and other grains. That said, try to find a grain-free (or even a grain-inclusive) food without some kind of pea or potato! My dogs were on grain-free because it was recommended for Checkers' mast cell tumors. I spent two entire afternoons plowing through the ingrdients list of every high quality dog food I could find online looking for some without the offending ingredients. It's the impossible challenge. After another conversation with the nutritionist, we agreed that some pea/potato product is OK as long as it's not at the top of the Ingredients list. I was feeding Now, which has always been one of the best foods on the market. The second and third ingredients are potatoes and peas. Another exhaustive search of ingredients online revealed two foods I could use. One was Petcurean's Go Limited Ingredient Lamb (not grain-free) and the Nutro line of foods, which does have some pea products but pretty far down the Ingredients list. I tried the Go for Flurry, who refused to eat it. Next I went to Nutro, which is not grain-free, although they do make a line that is, so the decision became which is the lesser of two evils: grains, or heart problems. Lacey already has a heart murmur. I settled on the Nutro Ultra line, which includes high quality grains and no peas or potatoes. I'm sharing this because the whole process took me several weeks of research. I encourage everyone to take a look at your food bag and see where on the Ingredients list pea and potato products fall, if you're concerned about the recent FDA news on dog food. Like by-products, wheat, corn and soy which we all avoide like the plague, we now have to add peas and potatoes which should not appear in the top 5 ingredients in your food. I'm in the process of transitioning everyone to differnt varieites of Nutro. So far, it's a success. Even my picky eater Flurry is eating it. I hope I've finally found a keeper!
