Innova Pet Food offers grain-free Innova Prime diets and treats. The food for adult dogs and cats contains poultry, red meat or fish as well as fruits and vegetables. Carbohydrates come from peas or lentils instead of grain to offer a lower glycemic index for sustained energy, the company states. Also added are healthy fats and oils, such as sunflower oil, flaxseed oil or menhaden oil, according to the company. The HealthBar Baked Dog Treats are sourced exclusively from either poultry or red meat, the company reports. The dog food is available in 5-lb., 12-lb. and 25-lb. packages and the cat food in 2-lb., 5-lb. and 12-lb. packages.
