Long Island’s superdogs will be heading to the North Fork this weekend to prove they can do more than roll over and shake hands.

Dozens of dogs from across the Island are expected to compete at the first North Fork Dock Diving Weekend. Pit bulls, golden retrievers and other water-loving breeds will be diving off a dock into a 20-by-40-foot pool. Three events test their ability to jump far and high and swim to retrieve a toy.

“Most of the dogs on Long Island swim anyway, so why not get them into a competition?” says Kim Loper, owner of Harbor Pet in Greenport, which is co-hosting with Greenport Harbor Brewing Co.

Pet owners can bring noncompeting dogs (as long as they are leashed and well-behaved), shop for pet supplies at 15 vendors and purchase food and beer. Pet experts will be on hand to answer your questions.

Here are four canine contenders expected to make a big splash at the dock-diving pool.
