As the image shows, there are bite marks on the corners, but I think it's still usable. This is a puzzle toy that allows your dog to have fun while searching for their favorite treats. Hide treats in the pieces and let your dog use their nose and paws to find them. Praise them a lot when they find them. By praising them, they will repeat the game, which will improve their sense of smell and intelligence. It's also effective for senior dogs who can't exercise, as it provides mental stimulation and helps prevent cognitive decline. We played with this one first, and then moved on to ones with more pieces as they got used to it. Thank you for your understanding.
