Treats on a Leash is proud to carry Paw 5 in Ames, Iowa. PAW5 began in 2015 with a simple problem: co-founder Dennis O’Donnell was trying to find an easy-to-use, but challenging feeder for his yellow lab, Dory. Some products were challenging, but were also messy and difficult to fill. Others were easy to fill, but more frustrating for Dory than they were engaging and enriching. So we built a team of dog-crazy people, and together made the Rock ’N Bowl - an easy-to-use, easy-to-clean puzzle feeder that challenges and engages dogs in their most natural behavior.
