Subjective Tone, in the context of the Play+ training methodology, represents the dog’s internal emotional and mental state in response to a prehended cue or situation. It is the ‘feel’ of the moment as perceived and experienced by the dog, which can range from excitement and anticipation to fear or confusion. The Subjective Tone is shaped by the dog’s past experiences, current feelings, and future expectations. It directly impacts the dog’s behavior, engagement level, and ‘Subjective Aim’. Therefore, managing the Subjective Tone is crucial for creating a balanced, positive training environment that supports the dog’s well-being and learning process.
