Adorable crate… gets the job done for my 2 shih tzus (8 lbs and 15 lbs)!  They REALLY seem interested in their new house. I would not recommend this for an aggressive big dog. Fairly easy to assemble…all parts were labeled and numbered well! Took me 3-4 hours to get it together. This is size medium. Proud to say I did it all by myself! Husband offered to (halfway) help but I wanted to keep everything perfectly organized. Especially love the French door style doors on the front. I changed out the cheap doorknobs. Happy with this purchase!
