All 304 Dog Hoodies are made from 100% cotton with a super soft fleece lining for maximum warmth and comfort. Designed with practicality in mind, a small opening under the hood allows the lead to easily fasten onto the collar underneath without the need to remove the garment. This Hoodie features a 304 Reflective logo on the back which not only looks super cool but it is highly reflective against any lights so adds some extra safety to your dog.  Please kindly be advised that our sizes refer to the detailed size chart below, rather than the actual physical size of the dog. We would like to encourage our customers to take accurate measurements before making their size selection - this will ensure your pet has a comfortable and accurate fit.
