Dog Wheelchair with Chin Rest Cushion

I purchased this about a month ago.
It is a 4-wheel wheelchair made by Himawari.

My family dog, who had his back right leg amputated, used it. However, his condition suddenly worsened, and he recently passed away over the rainbow bridge. I am listing it so that someone who needs it can use it.

It was used for about 1 week.

It has been rolled, but there may still be some fur remaining.
Also, it has been wiped with alcohol, but please refrain from purchasing if you are concerned.
The cushion was not used as a cone collar was worn, so it has not been disinfected.

Material: Aluminum frame

Size (main body part)
Total length: approx. 46cm (dog's torso 35-37cm)
Width: approx. 15.5cm (dog's body width 12-14.5cm)
Height: approx. 22cm
Rear leg inseam: approx. 19.5cm (can be lowered by about 2cm with belt adjustment)
Weight: up to approx. 4.5kg

I am not knowledgeable about wheelchairs, so I cannot answer technical questions.
Please use my dog's measurements as a reference for sizing:

Weight: 4.3kg
Shoulder width: 12cm
Hip width: 8.5cm
Torso length: 36cm
Body height: 25.5cm
Front leg inseam: 16cm
Rear leg inseam: 19.5cm
Distance between front and rear legs: 16.5cm

This size fit perfectly.

The inseam can be lowered but not raised, so dogs with longer legs cannot use it.

The chin rest attaches with Velcro.
Belts were added for a 3-legged dog.

I don't have anything to measure the weight, so I don't know the exact weight, but it is very light and he walked smoothly on his front legs.

I may not be able to answer questions like Can my dog use this size?, but I will answer any questions I can within my knowledge. Thank you.

I am afraid to disassemble it, so it will be shipped as is, in a cardboard box made from cut and taped pieces.
(It will be more like wrapping it in cardboard.)

Since I am out of town, shipping will be after December 2nd.
