Four Corners Expos helps non-profit pet rescues from all over the Four Corners area by donating expo space to them to promote, recruit and conduct pet adoptions. This year’s Pet Expo will feature Dockdogs, an international canine aquatic competition. Dockdogs will hold competitions Saturday and Sunday. There are three categories of competition: distance, height and speed. Anyone may enter a dog by visiting Dockdogs.com, or registering at the venue at 9 a.m. the day of the event.
