Yesterday marked the anniversary of the invention of the Frisbee in 1957, and on behalf of all those sporty pups out there, hip hip hooray! The term is actually trademarked by Wham-O and is thought to be a play on the name of Frisbie Pie Company in Bridgeport, Conn., whose pie tins were used by Yale University students on the campus for similar purposes. For this reason, all those discs out there (and disc competitions) cannot officially be called Frisbee Dog. Many popular toy brands, including Nylabone and Kong, have discs for doggies that want to get into the game. My fave is the Aerobie Dogobie because it's floatable, flexible, and puncture-resistant, but still soft enough for gentle catches in your pet's mouth.
