Diving, weaving and flying canines from across the world impressed crowds on Saturday at the National Finals of the Purina Pro Plan Incredible Dog Challenge. The event, now in its 16th year, takes place at Purina Farms in Gray Summit, Mo.

Vhoebe, a 5-year-old Belgian Malinois from San Diego, deftly defended her dock diving title. She fell just three inches short of matching the world record she set last year at the National Finals: 32 feet, 3 inches. Huntmoor Diamond, a Jack Russell Terrier from Springfield, Mo., is eight years old — and has won the Jack Russell Hurdle Racing contest every year for the past five years. Not a bad run if you ask us!

Cowboy, a Chesapeake Bay Retriever from Paw Paw, Mich., competes in the Fetch It demonstration on Saturday. Cowboy took first place and set an event record with a jump of 23 feet.

Kate, a Border Collie from Florida, took first place in the large-dog agility category.

Andrew Han and his Australian Shepherd, Solar, compete in the Freestyle Flying Disc competition.

Our friends at Purina estimate that 500 spectators showed up to cheer on their favorite canines. And since there's clearly no shortage of tweets, Instagrams and Vine videos, we're guessing they had a great time.https://youtu.be/k4XCYVjXV-M
