We are grateful to have this crate that gives our mastiff, Gus, plenty of room. Unfortunately, Gus chewed/scratched the bottom mat in a couple of weeks. This is typical of all the prior crates we housed him in too. So my husband made a new bottom for the crate that Gus has not destroyed yet. This is the first crate we have purchased that gave him room to turn around and stand up in. Overall, we are very pleased with the crate.
