Aluminum dog wheelchair, adjustable and ideal for walking assistance. - Type: Dog wheelchair - Frame material: Aluminum - Wheel type: Front caster wheels, rear fixed wheels - Size: XS, adjustable - Purpose: Walking assistance Thank you for viewing. Used for a 13kg Shiba Inu. It was an XS size, so it was small for a Shiba Inu, but I used it by extending the height and width to the limit. The目安 (guideline) is a rear leg height of 19-35cm when standing, a width of 14-22cm, and a weight of 4-10kg. I believe all the parts are present, but it's difficult to confirm, so everything in the photos is what you'll receive. It will be disassembled and shipped in the original box, so please assemble it for use.
