Unlike other more sedate dog events, like the Westminster Kennel Club Dog Show, which is more like a beauty pageant, this contest, held last weekend in Chattanooga, Tennessee was pure athleticsm. Running. Leaping. Catching. Or, as organizers put it, "Rather than prancing on carpet ... these amazing canine athletes gouged out chunks out of turf as they raced to snag spinning flying discs in midair."
