PROMOTES HEALTHY EATING HABITS: This rolling feeder dog toy has been designed to keep your dog entertained and mentally stimulated. Combining the challenge of a puzzle toy with the reward of a snack increases the fun of playing and encourages your dog to eat slowly, which has a positive effect on their digestive health. Rewarding your dog with a snack while playing not only stimulates his body but also his mind, promoting intelligence and brain development. SAFE AND DURABLE: This pet treat toy is made of high-quality ABS food-grade material that is safe, non-toxic and environmentally friendly. The sturdy construction ensures a long lifespan, and the entire design is round and smooth with no sharp edges to hurt your pet, ensuring safety while playing. SUITS MOST DOG FOOD: You can adjust the size of the hole that the food falls out of to suit your needs. You can fill it with your dog's favourite treats or snacks to keep him interested, and the food falls out smoothly without getting stuck while he plays. Suitable for small, medium and large dogs. ENHANCE MENTAL TRAINING: Dogs can use their keen sense of smell to sniff out the food in the toy's food hole and then use their nose or paws to set the toy in motion. This trains their intelligence, burns off excess energy, stimulates their minds, provides mental variety and keeps them active and motivated. EASY TO USE AND CLEAN: Very easy to use: a. Open the lid of the small food box; b. Put the food in the box; c. Cover the lid and adjust the food to the right size; d. Let it roll.
