This ball is a perfect chewing toy, but it also can serve as a treat dispenser. A special inner compartment stores treats and kibbles, which are difficult for the dog to get out. Thus, it will encourage mental and physical stimulation and make the process of feeding longer and healthier. Occupied with challenging mealtime, your Bullmastiff will take care of his dental hygiene: teeth are cleaned and gums are massaged.
There is no need to worry about the dog's health, as the rubber is safe for the dog. It doesn't contain any harmful substances, so it won't cause allergic reactions. Cleaning won't take you much time - it is possible to wash it under the faucet or in a dishwashing machine.
