I bought it used for 10,000 yen. I've used it about 20 times in the past 2 months. I've probably only used it for a total of about 3 hours since I bought it. It's very lightweight, and the rear tires are casters, so it's easy to maneuver. I don't know because I haven't used anything else, but I feel like it's for indoor use because the wheels are small. I'm not using it now because my dog is bedridden. I think there is some dirt. I rinsed it with a shower, but there may be some dirt or hair remaining. I used it for a 7kg Shiba Inu. I think it's suitable for small dogs to small medium-sized dogs. If the height is right, it might hold up to 10kg?? The chin rest is fixed with a lock tie. You can adjust the position of the chin rest depending on the size of your dog. Of course, you can also use it without the chin rest. Everything in the photos is included. I will disassemble the chin rest and shorten it for shipping. The legs with the wheels cannot be removed. Caring for elderly dogs Rehabilitation Wheelchair Small dog Medium-sized dog
