We need to educate dog owner's to teach their dog's not to run or even jog (only walk) on hard surfaces like footpath's. Because dog's dont have feet like us, they only have a heel and toe's. When a dog runs on a hard surface it's like us running on our heels (OUCH!), it can fracture their heel's. We need to teach man's best friend to only run on soft area's like grass, the beach, river sand, dirt tracks, etc.
