Handmade dog cart cushion. The filling is 100% polyester, so it can be washed. Hand washing is recommended to prevent deformation. Please shape it before drying. Why not create an original cart cushion with your favorite fabric? Please let us know the desired finished size. If you don't mind, please tell us your dog's breed, name, and gender. We accept custom orders. The finished size may vary slightly depending on the amount of filling. Please understand. If you would like a fabric other than the samples, we will post the fabric, so please let us know. If you choose two fabrics, you can use it reversibly. If you would like non-slip fabric, please let us know. An additional fee of 600 yen will be charged for non-slip fabric. Please understand that this is a handmade item, so there may be some stitching errors or distortions. Please purchase with this in mind.
