Slip Collars (Choke Chains)
Perhaps the most common slip type dog training collar, a slip collar is designed to allow the trainer to quickly close and release the collar around a dog’s neck. Dogs learn to not repeat a behaviour when they feel the chain close.

A slip collar for training dogs must be put on a dog properly, with the end coming from the lead around the back of the dog’s neck. This allows the chain to quickly slacken when released. When training, quickly tug then add slack to the lead whenever you need to correct behaviour.

The consequences of not using a slip collar properly can be disastrous. Do not pull too hard on the lead, just enough for your dog to take notice. Also, you should not keep pulling on the lead for an extended period.

Prong Collars (Pinch Collar)
Similar to a slip collar in design, prong collars have prongs on the inside of the collar. When the lead is tugged, the prongs pinch the dog’s neck. Unlike a slip collar, a prong collar has a limit to how much it will close around a dog’s neck.
I consider these to be barbaric and I do not recommend them

Although it is often stated that a prong collar, with a limited circumference and by evenly spreading pressure all around a dog’s neck, is at least as safe as a slip collar, I think this is untrue since it is very easy to damage a dogs neck by misuse of a prong collar.

E-collar (electronic collar)
An e-collar looks similar to a regular dog collar, but it is equipped with an electrical system that can deliver a sensation to the dog. Using a remote control device, a trainer can deliver a small charge through the e-collar whenever behaviour needs to be corrected.

An e-collar is an ideal way to train your dog off-leash. Incorrect behaviour is addressed immediately, so your dog quickly and easily learns the correct action, without needing a lead on which to tug.

In all cases, it is important to only use dog training collars only when training and while you are paying close attention to your dog. Leaving a training collar on when you are not working with your dog could lead to serious accidents. Each time you finish training, remove the training collar from your dog and replace it with the regular collar.
On the whole I suggest that the careful owner could use a slip collar for training dogs as the alternatives can be disastrous if the dog is unattended.
REMEMBER you must NEVER jerk a slip collar when the dog is wearing it.
An e-Collar is preferable and your dog will quiclkly get used to it.
