This is our sheltie's favorite toy! His ball has held up to daily fetch, chewing and bouncing. Ordering another because it goes lost from time to time and he misses it till it's found.The ball is a good size and somewhat solid so it makes it NOT so easy for the dogs to puncher.The squeaker however dies rather quickly.Just a much better toy for the dogs.Our lab literally jumped up and down before I even got the ball out of the package! She’s had it in her month almost constantly. Seems sturdy and so far has escaped damage from our chewing loving lab.First ball didn’t squeak. Replaced and told not to return defective ball.The ball had a seam in the middle and the ball literally split in half after my 5 month old puppy chewed it after a week. Furthermore, the squeak apparatus stopped working before it split!!!0 Stars!!!!Durable lasted several months of playing with a full grown German Shepard. But the squeaker doesn’t last very long, I prefer without it because it’s so loud so fine for me.The squeaker didn't last 3 minutes and my dog was not aggressive with it. For the money - it should have lasted.Still in one piece and sqeaking!
