Performance Pet Products Spring Naturals whole grain and grain-free dry dinners have been certified low glycemic and diabetic friendly by the Glycemic Research Institute. The super-premium brand is the only made-in-the-US dog kibble to receive this accreditation, according to the company, due to its philosophy of using only real meat, poultry or fish as the #1 protein source rather than rendered meals.

Dry petfoods that use rendered meals require a binding agent that is high in simple carbohydrates and starches to hold the kibble together, which converts rapidly into glucose. A diet full of carbs and starches can be unhealthy for pets because the higher the carbs, the higher the glycemic index. Since Spring Naturals doesn't use meals, the brand's dry dinners are free of high-carbohydrate binding agents such as wheat, soy, tapioca, white rice, brown rice and potato starch.

"We couldn't be more thrilled about achieving this certification," said Rob Cadenhead, vice president of sales and marketing at Spring Naturals. "Now consumers know just how healthy our dinners are and that we are dedicated to providing the best nutrition for their beloved pets."
