Convenient for Training Your Dog: You can keep your treats ( MuttBalls® Minis ) close to you by having it clipped on. That way you can instantly reward your dog with a MuttBalls® treat during training! Timing is everything with training so let this tool help you. Magnetic Closing Automatically: There is a small magnet inside the silicone on both sides of the opening, so it allows you to do everything with one hand and get to the treats easier. Easy access is what you want to be able to reward your dog with a MuttBalls® Mini! Easy To Wash: This silicone dog training bag is not easy to deform and you can wash it easily. Thawing The MuttBalls Overnight: This process has become easier now with the MuttBalls® Pouch. Our blue pouches can store 2 regular MuttBalls® or 6 Mini MuttBalls® . Put the frozen MuttBalls® in the pouch, then put it in the fridge and take it out the next day.
