This Hot Dog(TM) is one bad dog! Fool those educated coyotes. The mouthpiece detaches from the horn to sound like two distinctly different coyotes. This will give you the edge during mating season and battling over territorial boundaries. The Hot Dog(TM) is super loud making it a great locator call. It's also versatile enough to create distress calls of birds, cottontails, jackrabbits, pups, fawns, and deer. This large howler's mouthpiece alone creates smooth-sounding howls. The horn adds rasp and volume to your calling. The Hot Dog(TM) is designed specifically to Speak The LanguageA(R) of the coyote.
