While this is just the right size for my golden retriever dogs, it was very difficult to hold up the sides while filling the pool!My dog loves to climb in and make circles (always counter-clockwise, about 3 or 4 circuits) and eventually lay down to cool off in our 110°F days here in Las Vegas while we swim in the 'adult' pool, but to get this one filled up the side walls keep falling back in.We've learned to set up about 3-4 big bricks inside to hold up the walls while filling.Now... the drain thing won't drain it all. its about 1" or 2" too high. Nonetheless, you can drain it that far and then flop it over to drain it all.For some reason, tree leaves, bugs, dog scum, who knows what else.... seem to make this pool (and probably all other versions as well) so dirty, scummy, scuzzy, etc! So, one must drain often, blast out with a hose, and... we've found we have to scrub it with a good sponge to get it clean!My dog loves this pool and if it came in a bigger size I would swim in it with her!It seems to be losing a little water underneath. It also does not have a true hose connector as it states..Pool was sturdy at first, but didn’t stay as well after my dog got in and out several times. Pool not as easy as I thought to fold up real fast and fit in the bag it came with, but easy to fold and put elsewhere. Overall good pool for the price and too cool off my pup in the heat.The one we bought would be too small for her to play in, but great for her to stand angrily while we bathe her. Good quality!Ordered last year. Didn't open until this summer. Dog walked through once to clean paws. After only two months of use pool leaks!Big enough for me and my Giant Beast ❤️My dog's love this pool we have a large German shepherd husky mix and there is more then enough room for him to lay down and play
