The WeatherBeeta Windbreaker 420D Deluxe Dog Coat is designed with a strong 420 denier showerproof outer shell with boa fleece lining for warmth.
Other benefits include a full wrap belly closure which is perfect in cooler months, an extended collar for extra protection and a harness hole for convenience.
Measure your dog from the base of his/her neck (roughly where the collar sits) to the base of his/her tail for sizing estimate.
