An animal training and behavior altering device and method is used to teach and train dogs, cats and most other animals from unwanted behaviors such as continuous barking, jumping up, stealing, pet to pet confrontations, unwanted use of furniture and other bad habits and behaviors. The device and method combines sound and smell to trigger senses of the animal in a manner that establishes and reinforces negative feedback. In particular, discharge of a propellant through a specially designed nozzle on a canister creates a loud hissing sound combined with a citrus scent that most animals strongly dislike, whereby the behavior of the animal is corrected.
