This is my second Tucker crate, I am still using the first extra large crate that I bought for my dog that has anxiety issues and is as strong as an ox plastic crates and other metal crates he’s just torn apart and has gotten hurt from. I highly recommend this crate especially if you have an anxious dog. This 42 inch crate is going for a calmer dog golden retriever. I assembled it by myself even the extra large one no problem.
