OCEANSIDE, Calif., Nov. 23, 2016 /PRNewswire/ -- There was another victory in Iowa. It was someone who greets his supporters with a tail wag, slobbery kiss, soft furry cuddle and a sandpaper tongue. The now world famous dog, who at the ripe old age (for a dog) of nine and a half, celebrated his big win at the 2016 DockDogs World Championship which just finished its fourth and final day in Dubuque, Iowa. Rex, a Belgian Malinois, is a tail-wagging resident of Oceanside, CA. Rex and his handler, Lianne Shinton of IQ K9 Training, have competed in the acclaimed competition upwards of 25 times, with 2016 being the ultimate win for the pair. Rex and Lianne now hold the International title for "Sonic Speed Retrieve" and the two were inducted into the Hall of Fame during a ceremony at the World Championship event.

Brianne Durham, a fellow DockDogs competitor and friend of the winning team said "they have shown the world that the underdog story is real. Rex came to Lianne as an unwanted orphan... And today he is a two-time World Champion! This journey for Lianne and Rex wasn't easy. The Championship didn't just happen. They've been there, every year for the last decade wanting this. So, when it finally happened, it was surreal. An incredible milestone in their lives together."
