Our Derby Collection Collars were designed and tested for the equestrian who brings their pup everywhere. Four legged BFF's should look just as stylish as their owners going from barn to polo matches. The luxurious leather padding for comfort and raised leather and fancy stitch make this collar a long time customer favourite. Features also include stainless steel hardware and a matching Pup & Pony signature logo. This collar pairs perfectly with our Derby Collection Halter and Derby Collection Dog Leash. Our products are hand crafted, and therefore the hole placement may vary slightly from product to product. Sizes 12-16 are an inch wide, while sizes 18-22 are just over an inch wide. To ensure best fit, measure dog's neck where collar would sit with two fingers under the tape. Our collars are measured by the first hole, to the other end of the collar (at the buckle). The leather will stretch over time, but for example if the measurement is 20 inches, then a 20 inch collar will fit.
