Mutt Waggin' Pet Supplies is proud to carry Give Pet in Medfield, Massachusetts. Our human Chris has always had a passion for dogs. And ever since his family adopted his first dog, Lummox, when he was five years old, he’s also been passionate about giving back to animal shelters. At first, it was just donating to the local shelter when he, his wife and three kids could. But after 112 years working in the premium pet food industry – that’s 16 in human years – Chris saw an opportunity to do something that could make a mastiff, er, massive impact for shelters nationwide.
