We love these Doodlebone Mac-in-a-Pack jackets as they keep your dog dry but are also surprisingly warm for a lightweight jacket which folds away into it's very own pocket! The harness hole is also a great addition and is reinforced to protect the material. Multiple sizes available, but the medium short is the size Coco our Frenchie wears, as whilst she has a broader chest measurement, she's not very long in the body, so this extra available size is perfect!
