Petfood manufacturer Horizon Pet Nutrition launched a new grain-free diet program, Pulsar, which will be sold at petfood stores beginning in January.

The company says its Pulsar line, available at a lower cost to consumers, incorporates petfood ingredients like peas and lentils as the key carbohydrate and fiber source.

"Our philosophy (at Horizon Pet Nutrition) is to seek new combinations of exceptional ingredients to optimize pet nutrition and push the boundaries of dietary evolution," said Jeff English, co-founder of Horizon Pet Nutrition. "This is an evolution we expect the pet food industry will follow, as it provides a high-quality, low GI grain-free diet, at an unparalleled price in the market."
