Assembled once and used only for a test ride. There are some scratches from assembly, but there are no problems with use. A detailed assembly manual was not included, so I assembled it while looking at the photos on the website. I purchased it for my 6kg, bedridden Toy Poodle, but I am selling it because he has paralysis in both hind legs and a curved spine, making it difficult to put him in. I think that a dog who can stand if supported, even if bedridden, will be able to enjoy it. Purchased in November 2025. Thank you for looking.
