The Junior Harness B is available in Pink, Beige and Black in sizes ranging from extra small to large. Matching leash is also available and sold separately. Please note that because these products were created with small/medium dog breeds in mind, larger sizes (i.e. Large, Extra-Large, etc.) do not necessarily mean larger breeds. Please refer to image of the size chart. Weight figures are for estimates only. Always use actual measurements.Please note that when measuring your dog, the measurement for the neck must be taken at the BASE OF THE NECK and chest girth must be taken behind the front legs. Also it is important to take into account the size of the dog's head as well as neck girth and chest girth. Since some dogs have a much larger head than their neck, please be sure that the neck opening is large enough to slide over your dog's head. It’s important to measure chest girth and neck girth of dog before customer purchase this harness. This harness would fit a dog with 11” neck girth and 14.5” to 15.35” chest girth.
