Size M Warm Note: Dog clothes size is not universal. We recommend that you measure your dog’s neck and chest circumference before purchasing. Leave a gap of 1 - 3cm to ensure a comfortable fit. You should consider your pet’s coat length and growth stage to determine if they need a larger size.

Easy to Wear: Button design makes it easy to put on and take off, hem design and fitted cuffs prevent the dog from escaping.
