Thank you for viewing my items from a wide selection. Width: Approximately 53 cm Back length: Approximately 12 cm Belly length: Approximately 15 cm Belly circumference: Approximately 42-45 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 depends on the thickness of the pad.) The outer surface is made of oxford fabric. The belly side is made of knit material. A thin fusible interfacing is attached to the center of the belly side. ✤ Due to many requests from customers ordering custom items to have no elastic, I have changed it to be without elastic. Please be sure to check your dog's size, considering the thickness of the pad you will be using, before purchasing. It is designed with a three-dimensional shape like a mask, so the important area is 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. I may change the design to address concerns such as whether the sanitary belt is burdensome for dogs or how to prevent urine leakage further. Thank you for your understanding. ★ If you are using the bulk purchase function, please let me know without setting the price.
