I got this one (free on trash day!) - and it is holding up fins so far. It is double lined/layered, sort of, so it should crack like the flimsy blue common design pool we used to have... Just broke it out for the first time this season and Ruby dug around in it... she doesn't try to chew on it tho... but I'd say this might be a good durable pool. It's actually called a sandbox, tho... Amazon.com: Ladybug Sandbox
