Rex® features a pleasuring long and shapely shaft, textured with veins and a tapered tip for those who want to feel what this Shepherd is packing. Leading down to a very pronounced knot, challenging even the most adventurous of pups, the reward of getting to tie with Rex® is all worth the bark to get there. Few other models can reach this depth of excitement, leading toward one of our more challenging knots to overcome! Let Rex® be the ride of your life, and feel just how great getting his kind of special treatment works out.
