Dogs are very playful and intelligent animals. Channel their energy and curiosity into something positive with TRIXIE's Chess Game. With four levels of play that require practice and concentration, this game is designed for the advanced canine game player. Level 1: Lift up cones. Design prevents cones from being knocked over. They must be lifted straight up. Level 2: Move multiple sliders using nose and paws to reveal hidden treat compartments Level 3: Stack on a second row of sliders that must be moved in the opposite directions from the first Level 4: Place cones between the sliders and use as stoppers Keep your dog challenged and curious by varying the number and placement of cones and treats. The non-slip rubber feet keep the game in place as your dog flips, slides, lifts and explores. We've also included an instructional booklet with tips and tricks for challenging and training dogs of all ages through play. Dishwasher safe. One year warranty. Measures 16 x 11 x 4 inches.
