This dog raincoat is made of 100% polyester fabric, which helps keep your dog cool, while the reflective trim ensures they are clearly visible at night and on particularly dark days. The leash hole on the top makes it easy to attach the leash to the collar without affecting the dog's comfort, making it convenient for traction and rain protection. The pocket can also double as a snack holder for particularly well-behaved dogs. We have 7 sizes to choose from to cater to dogs of different sizes. The 2XL-4XL of this dog raincoat is more suitable for medium and large dogs such as Labradors, Golden Retrievers, German Shepherds and Rottweilers. Note: Please purchase according to the size chart. If you are not sure about the size of your dog, you can choose a larger size. After receiving the raincoat, creases will appear due to long-term folding, which can be ironed at low temperature.
