GREENSBORO, N.C. — Millions of dogs suffer from canine arthritis and their owners often have no idea their beloved pets are in such pain. A new initiative spearheaded by Novartis Animal Health US, Inc. and Hill’s Pet Nutrition will combat that disconnect with a goal of screening one million dogs for canine arthritis. The two companies teamed up to launch the ‘Million Dog Search,’ a nationwide awareness campaign that will also raise thousands of dollars for animal charities, including Paws of Life.
