Custom-made 4-wheel walker, size S, for a 6kg toy poodle. Made of lightweight aluminum and adjustable. While the width is fixed, the height and length can be adjusted with the included wrench. I usually use a rear-wheel walker for ball games and meals, but this was used when my dog dislocated its front legs. Used indoors for a few months, but the chest cushion has cracks. This cushion isn't mentioned in the manual, so it might not be necessary, but if you do use it, you'll probably need a replacement. The blue band's Velcro shows signs of use (see photo 15). I apologize for the amateur inspection and explanation, but please refrain from purchasing if you have any concerns, such as the size not fitting. Thanks to this product, my dog's daily life improved greatly, and I felt like I saw more smiles. If it fits and can be used by someone... I will ship the product in the photos, the manual, and the wrench with amateur packaging. Returns are not accepted due to reasons such as the size not fitting. Please refer to the following site for details: https://wanwork.net/ (Note) As mentioned above, the chest cushion has cracks, as shown in photo 5. Width: 19cm (The width is not adjustable, so 19cm or more is absolutely impossible! Personally, I think a little extra space makes it easier to get your dog in and out.) Height: Adjustable up to ~32cm Length: Adjustable up to ~31cm Please check my profile. Thank you for looking.
