Figure-eight style halter of 3/4" nylon web with 1-1/2" metal throat ring. To determine size, measure figure-eight around goat's nose and behind ears. Order extra-small size for 29-31", size small for 31-34", medium for 34-38", and large for 39-42". Extra-small fits most grown Pygmies and small goats; small size fits most does and small bucks; medium fits large does and most bucks; large fits large bucks and really large does. Some bucks are too big for even the large size halter; be sure to measure. If size isn't specified, medium will be sent. Green, red, blue and black color choices.
