prong collar Hi, I have a 60 lb Boxer who used to take ME for a walk until I used the prong collar( I know it as a "pinch" collar) It can also be used for other training issues. It looks medievil but is actually safer than a choke collar. A choke collar can damage the dogs trachea if it pulls too hard. I now take Bronson for a walk, not the other way around! Good Luck!
