In contrast to conventional clickers, the volume and pitch on the Multi-Clicker can be adjusted. The principle is simple: Programme your dog to the acoustic click-tone signal – look for an appropriate volume for your dog. This signal tone method has one great advantage over other educational appliances: You can get along without the use of punishment. Neither screaming and cursing, nor violence are needed. Absolutely no aggression is communicated from master to dog at all. Also suitable for cats and horses! With training instructions.
