Is your dog begging for glory each time he barks? Does your hamster wheel furiously squeak away as your furry friend rigorously trains for a race he may never run? Let them compete! Pit your pets against others at the Petco Invitational in a day of races, eating contests, feats of discipline and prizes. Their lives are short. At least allow them to be the champions they are for this one day. 10 a.m.-2:30 p.m. Petco, 8070 Concord Mills Blvd. 704-979-1952.
