Hazel - if you get the one without the handle it should be quite durable. Cody has been chewing the handle on the one we have, and just him alone has nearly taken it off
We have another one which came with a rope through the middle - we took the rope out and that one has been around for a year with no damage. Cody is obsessed with Jolly balls, and Nova can't quite figure out what all the fuss is about (but then again the balls are a little big for her to carry lol)
