People don't always realize that when they run or bike with their dogs alongside, even young and/or healthy dogs are at risk for heart attacks. Their physiology requires them to do short sprints with frequent breaks, and they require more water than we do.
You can slow down or take a break when you're out of breath, or feel weak, but your dog will try to keep up with you at all costs, even if their lungs or hearts are telling them to stop, or if they're in need of water, and their distress isn't always obvious.
Also, where's the fun for them when they can't visit or play with other dogs on the trail, or just sniff stuff along the path?
