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.

Picky dog approved!

I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣
