Our 6 month old puppy went crazy with donkey! You would think there was something in or on it he wanted. Not sure how durable over time it will be. Materials look substantial. Bought 2 and held one back. Even if it doesn’t last long I will definitely buy again as no ther dog toy has interested him so much. It is not large… which is ok for us.
