Martingale collars (also called limited-slip collars) are usually made of flat nylon with a smaller fixed-length section (made of either nylon or a short length of chain) that, when pulled on by the leash, shortens up tightening the collar around the dog's neck, to a limited extent. When properly fitted, martingales are looser than flat-buckle collars when not tightened, and less severely corrective than slip collars when tightened.
Electronic collars (also known as E-collars) transmit a remote signal from a control device the handler operates to the collar. An electrical impulse is transmitted by the handler remotely, at varying degrees of intensity, from varying distances depending on range frequency. It is also done automatically in the bark electronic collar to stop excessive barking, and invisible fence collar when the dog strays outside its boundary. Electronic collars are widely used in some areas of the world and by some dog obedience professionals. This technique remains a source of controversy with many dog training associations, veterinary associations and kennel clubs.
The training takes place around a set course, and if on a competitive level, training is carried out against the clock.
