i'd heard such good things about the canine coolers though, that i had to try another. this one, just purchased a year ago, is much more study. it came with instructions on how to fill it, maintain it & make sure i don't have air trapped in it that can help create leaks. so far its working well & hasn't leaked at all, nor been chewed on this time.
baka's cooling down from her nightly walk on it right now. so, we like ours very much.
