The prong collar is coated with chrome for long-lasting use, featuring rubber tips with blunt ends on the smooth, rounded prongs to avoid harm. This excellent training tool offers a robust yet secure alternative to traditional choke chains, being sturdily crafted from electronically welded steel for extra strength. Training with durability without causing pain. Note: Use a carabiner/extender leash to connect both the usual collar and the prong collar, ensuring you maintain control over your dog if the prong collar becomes loose.
