Had never purchased a crate before and bought this one for an 8-wk old very active puppy. That puppy is now just shy of 2-years and weighs 60 lbs and is 25 inches tall. This crate has worked out very well and is still being used in our bedroom. We have not put it up and down. My pup did manage to somehow get to the outside plastic handle and chew it up while locked in her crate...never figured out how she could do that. It only happened one time. She was younger and excited to get out she caught her paw between the plastic liner and metal, no damage to her, just scared her. She hasn't done that again. The only reason I didn't give the product "excellent" is because it "wobbles" a little when I move it around (without her in it) and that makes me uneasy. Maybe that's how crates this size do, don't know.
