Stimulating dog puzzle with a hollow treat chamber and an intelligence-boosting mechanism that trains problem-solving skills, supports healthy and longer interactive play sessions for sustained engagement. Easy care: dries quickly and features removable components for easy hand- or machine-washing, helping prevent unpleasant odors over time. Gum-friendly design: soft plush texture protects the gums, reduces injury risk and prevents swallowing. Safe interaction with the squeaker during active play. Stress-reducing sound: built-in sound element captures the dog's attention, increases engagement, and encourages natural exploration. Helps promote a balanced, happier pet. 2-3 practical use scenarios - Mealtime enrichment: hide treats inside the hollow chamber to extend feeding time and stimulate thinking as the dog works to retrieve them. - Solo play or daycare: a stimulating activity that occupies attention and reduces boredom when you’re not directly interacting. - Training and interactive play: use during training sessions to reward problem-solving and self-control while enjoying the squeaker and engaging sounds.
