~The Nina Ottosson Dog Smart is made to look like real wood, but its unique composite material has all the benefits of both wood and plastic and is more durable than real wood. TRAIN WITH TREATS: The Nina Ottosson Dog Smart is an entry level dog game that challenges your dog to uncover treats while helping them to develop new learning techniques. As a Level 1 Dog Game, the Dog Smart is great for introducing your dog to new puzzles and games while preparing them for more exciting and challenging games to come. HOW TO PLAY: Place treats in compartments of base. Cover treat compartments with pegs. The more compartments that are covered, the harder the game will be. Show your dog where the treats are and watch them find the tasty reward! Dogs are smarter than you think. Sometimes we just need to teach them! Leave some compartments uncovered for your dog to gain interest. EASY TO CLEAN: To wash your dog's Dog Smart, simply remove all treats/kibble and hand wash with warm soapy water, rinse clean and dry.
