David Letterman hosted the Purina Pro Plan Incredible Dog Challenge on The Late Show because he loves doggies!
The whole point of the incredible dog challenge is to have dogs compete in agility, racing, disc and diving events!
These dogs are true athletes who are loyal, competitive, smart and super talented!!
Letterman hosted a cool segment where doggies were competing against each other to see who could dive the furthest.
It's so incredible! These super obedient dogs listen to their masters then perform incredible athletic feats!
These pups can jump well over 20-feet with ease!!
Check out the video (above) to see which doggy can jump the furthest!
