Which tone is described as pleasing and joyful?

The praise tone is characterized as pleasing and joyful because it is specifically used to reinforce positive behavior or performance, particularly in the context of working with a narcotics detection dog. When handlers use a praise tone, they are expressing approval and encouragement, which boosts the dog's confidence and strengthens their bond. This tone often features a higher pitch and a more enthusiastic rhythm, making it sound celebratory.

Using a praise tone can lead to increased motivation and focus for the dog, enhancing their ability to perform tasks and respond positively to commands. This approach builds a solid foundation of trust and teamwork between the handler and the dog, ultimately leading to more effective performance in narcotics detection work.
