Made in Japan Custom 4-Wheel Dog Wheelchair

Miniature Dachshund, 4.7 kg.
Purchased for 20,000 yen for my male dog.
Custom-made in Japan.

Made to the following specifications:
It was only used indoors, so I don't think there are any noticeable stains or scratches. I've cleaned it with disinfectant wipes, but there might be some overlooked spots, so please refrain from purchasing if you are sensitive.

Back length: [47 cm]
② Body height: [14 cm]
③ Leg height (from ground to crotch of hind legs): [18 cm]
④ Center of body to tip of leg: [14 cm]
⑤ From front leg crotch to hind leg crotch: [17 cm]
⑥ Body width (measure at the widest part): [15 cm]
⑦ Weight: [4.7 kg]
It was custom-made to these dimensions, but since the front legs were unstable, a friend modified it by adding front wheels to make it a 4-wheel model.
