"PULLER was developed by professional cynologysts as an innovative training shell for dogs. A special set of two purple PULLER rings and a set of exercises with it will provide daily interactive training for dogs and all the necessary physical activities, so the dog owner doesn’t have to spend a lot of time on walking.
Why are there TWO rings in the set? Is one of them is the spare?
PULLER for a long time was carefully developed by cynologists and recommended for use as a set of two rings. The second isn’t the spare. Working with two rings at the same time, the dog and its owner maintain constant contact during the class. The dog is accustomed to switch quickly from one object to another (from one task to another) at a high rate of work. This in turn provides the foundation for any subsequent training programs. By using both rings at the same time, you can increase the efficiency of your practice by keeping your dog’s interest in it all the time.
If you do “save” or decide to simplify your classes and use only one ring, you will not get the effect of training. A complete set of training and development of a dog is possible only with the use of a set of two rings."
