If dogs have a not so thick coat, a dog jumper can help to keep the dog warm. In addition, a dog jumper can protect the dog after an operation on the wound. A dog jumper keeps the dog nice and warm, for example if the dog does not have a very thick coat. A dog jumper can also provide protection after surgery. The jumper has a reflective strip so that the dog is easily visible in the dark. The fabric is slightly stretchy and therefore comfortable for the dog. The zipper is located at the top of the jumper, which ensures that it does not bother the dog. It is also a double zipper, which makes it easy to attach a leash to the collar or harness.
