Nestl é Purina PetCare has launched protein and carbohydrate bars for dogs, tapping National Football League quarterback Eli Manning as a spokesman.

St. Louis-based Nestlé Purina, maker of Beneful and Alpo dog food, has expanded its lineup of nutritional supplements with two new bars for dogs, Purina Pro Plan Sport PRiME and ReFuel. The pet food giant began selling the products earlier this month in specialty stores, including PetSmart and Petco.

Nestlé Purina, a unit of Swiss-based Nestlé, signed up two-time Super Bowl MVP Eli Manning to help launch the bars in New York on Wednesday. It’s the first time the pet food maker has partnered with the Giants quarterback.

Manning said he went on hikes and runs with his dog, a 4-year-old Cavalier King Charles Spaniel named Chester. “He gets a lot of activity,” Manning said in an interview.

Nestlé Purina held the “Purina Pro Plan MANning vs. DOG Challenge” in New York Wednesday afternoon, with Manning participating with dogs in physical challenges, including flying disc and speed races.
