Herm Sprenger prongs mounted on an adjustable Martingale cover. 4 prongs on each side. Prongs are removable, so fewer (or no) prongs can be used. These covers allow for wider space near the throat with prongs on the neck, where they are most effective. Proper fit is high on the neck.
These collars are made to use for a quick correction tug and release, not for constant pressure.
Covers are 1½" wide with your choice of 4 Jaquard ribbons, 1" side buckle closure (Weiner lock I consider the best) and nickel hardware. Choose ribbon color and prong size (2.5mm or 3.0mm). Ribbons from left to right are: flowers, green, multi-colored weave and red.
