Dog wheelchairs and walkers. XS size. Height: 19-35cm Width: 14-22cm Dog weight: 6-12kg Photos 6 and later are reference materials. Purchased new in April 2024. Used for a 14-year-old Corgi, 10kg. It seems to be an overseas product, and the manual is an English pamphlet. I assembled it while looking at the image photos. Height, etc., can be adjusted with the included tools. Adjustment is necessary to suit the dog breed. It seems that 2-wheel and 4-wheel use are possible. When shipping, I will remove the tires to prevent damage during transit and pack and ship them separately.
