The Comfort Coat, though lightweight, is very durable. However, it is not indestructible. We do guarantee that the seams will not come unstitched. In fact there is a full exchange warranty against manufacturing defects.
The 4 ways stretch material is of high quality and has such a large amount of stretch it will move with your dog. If the material becomes punctured, it will not run–the hole may slightly increase if not mended. We have created some iron-on patches for the Comfort Coat that you can put on at home! So, let us know and we can send some patches if needed.
