It has been survived by American Bulldogs and now a stray pit that showed up. Everyone that i have given one to for their dogs can't believe it doesn't get destroyed. Not one tooth mark has gone through this ball. Love it for play. The one thing to watch out for is don't let it get stuck at your metal door. Had a hard time getting the door open to go out on deck because the ball was up against door. This is the best ball out there.

Our Shepherd Ives this ball! Handy to put in treats off and on

I bought the Medium and Large of these Balls my Staffordshire Bull Terrier loves them when he found out they were dropping dog kibble it was hilarious he dropped the ball ate the kibble peice then pick the ball back up squeeze and drop the kibble he dropped the ball and ate the kibble he was chewing it leaving a trail of kibble were he was running and playing with the ball when he seen the 100 foot trail he left the ball and started eating the trail of kibble then went back playing with the ball.. I'm thinking I getting 2 more one Medium and 1 large because you can cut the tabs out to make the balls work with bigger snacks like treats instead of kibble my dog loves it also has held up well to my dogs chewing habits which he is a Staffordshire Bull terrier
