Slip Collars, also called Choke or Chokers
This is one of the oldest styles of collar often made of chain or nylon. The collar slips over the dog’s head and squeezes the neck when pulled. This is an older style and has been replaced by newer models.
Prong or Pinch Collars
Pinch collars have points that press into the dog’s neck when pressure is applied. Pinch collars were designed to control unruly dogs. Advances in training and equipment now offer other more humane options for feisty dogs.
Electronic or E-Collars (also called Stimulation Collars or Shock Collars)
These are used for underground or electric fence training, barking problems and other types of training. The system consists of a collar and a battery-operated receiver that corrects the dog with either a warning noise and an electrical shock.
Note: Training collars or shock collars should not be used by a new dog owner or by trainers who are not properly trained in their use. Use of these collars can result in trauma to your dog and is generally not recommended by positive reinforcement trainers.
