Who’s good boy? Who’s a good boy? If you know it’s you, then you deserve to reward yourself with a real treat – one of our novelty silicone dog tail plugs that actually wag as you move your butt. These are made of flack silicone with no fur, attached to a plug that fits tightly inside the butt, so that there is no chance of it falling out due to vigorous tail wagging. Your master is sure to give you lots of treats if you show up to your next rendezvous with this fantastic tail greeting them!
