I purchased two matching sets for my Frenchie boys. Not only do they look cute as can be; both of my boys are comfy as these fit them perfectly! We have several other “Frenchie” harnesses from several different brands but you cannot bet the fit and the quality of Beast and Buckle! My one boy is 25 pounds with a very athletic build and wears a large and my other boy is pushing 35 pounds with a very stocky build and wears an XL. I’m so happy and impressed with all of my purchases from Beast and Buckle!!
