Thank you for viewing my items from a wide selection. Width: Approximately 41 cm Back length: Approximately 10 cm Belly length: Approximately 13 cm Belly circumference: Approximately 30-33 cm ✤ The size of the sanitary belt is measured from end to end of the tape. You can adjust it, so there is about 1-2 cm of leeway. (This may vary depending on the thickness of the pad.) The outer fabric is oxford cloth. The belly side is made of knit material. A thin fusible interfacing is attached to the center of the belly side. ★ This fabric is out of stock, so this is the last one available. Please be sure to check your dog's measurements, considering the thickness of the pad you will be using, before purchasing. It is made with a three-dimensional shape like a mask, so the important parts are not pressed against the belly, reducing discomfort. The navel area and the base of the legs fit snugly, making it less likely for urine to leak. ★ For dogs that need care, such as those who are actively roaming, the width has been increased to accommodate larger pads, and the elastic band has been removed to make pad changes easier ^⁠_⁠^ ★ If you are using the bundle purchase feature, please let me know without setting the price. This is a handmade item created as a hobby. There may be imperfections such as loose threads, unevenness, or slight size variations. Please refrain from purchasing if you cannot accept these potential issues. m(__)m
