If your dogs love water, they are going to LOVE this! I thought it looked fun, so i ordered the 67. I wish there was a larger size honestly, but it is fantastic! They absolutely love it! The water does get everywhere, but if you have a good spot for it youll be good to go. Very durable material. They played in it for 2 hours and i have no punctures. It has been even better than i anticipated. Easy set up, like seriously couldnt be easier. Lay it out flat, plug the hose in, turn the hose on. Awesome product, probably one of the best things Ive ever purchased.
