Measure your dog's back length from the base of the neck to the base of the tail, then measure the chest at its widest point, and match both to the size chart. The range runs from S to 5XL, so larger breeds are covered.

The waterproof PU outer shell means rain beads up and runs off rather than soaking through, keeping his back, chest and head covered. It's a cape style, so his legs and belly stay open for easy movement, which means a quick towel of the paws is still a good idea after a heavy downpour.

The cape design goes on over the head with no legs to thread through, so it's on and clipped in seconds. Most dogs barely notice it, since it sits more like a light cover than a full jumper.

A reflective strip runs across the coat and catches car headlights, helping your dog stand out on dark, wet roads when winter walks happen after sunset.
