Mental stimulation is just as important as physical activity and this cube toy from FOUFOUDANDS provides plenty of mental play. This activity is geared towards advanced level seekers who have already mastered other types of puzzle toys. Hide treats in the various folds and flaps for your dog to sniff out. Each side has a differently designed treat slot so the challenge is fun, stimulating and will engage their natural desire to hunt. It's sure to keep your dog busy and occupied which can help cure boredom, anxiety and destructive habits like chewing furniture. Best suited for a gentle-moderate chewer.
