I ordered this crate for my uber-monster MastWeiler puppy and he loves it! He is now coming up to 6 months, weighs more than 40KG, and still fits nicely into the crate, with a good bit of room for him to shuffle about, turn round and make himself comfy. He loves it that much I leave it "open" all day and he goes in for a kip under his own mastiff-power, and still has enough room for his best friend "Jake" the German Shepherd puppy (4 months old)to fit in too (although he does have his own!). There is a removable metal "tray" in the bottom of the crate which is easy to clean, doesn't clatter too much, so won't startle your dog. All in all a brilliant purchase and was delivered promptly, packaged well and is so simple to put up; it quite literally just folds out/flat, so is easy to move out of the room for cleaning up, decorating etc. I do advise caution as although easy to fold and put up, it is deceptively heavy!
