A variety of animals use a hissing noise to drive away predators and our Pet Spray Instructor uses compressed air to mimic the natural warning hiss that swans & other animals make, to help stop your dogs unnecessary habits. Timing is crucial in dog training. To ensure that your dog associates the sound of the pet instructor spray with their behavior rather than with you, it is recommended to keep the device at your side or slightly behind you.

The pet instructor spray should only be used when an Unnecessary behavior occurs. A brief emission should suffice to redirect your dog's attention away from any undesired behavior. To prevent excessive use, begin by addressing the situation in which the undesired behavior is most disruptive, such as barking at visitors.
