Our Rosie + Jo harnesses are made with care and attention to detail with their adjustable straps to ensure your pooch has a comfortable fit on their walkies. As a rule of thumb you should be able to fit 2 fingers between your dog's neck and chest for a perfect fit. 

Our harnesses come in a range of sizes from X-Small to Large. Please make sure to reference our Size Guide here for your dog's measurements prior to purchasing.
