Which reinforcement type helps a dog learn to perform without pressure from a leash by responding correctly to the handler's cues?

The correct answer is based on the understanding of how negative reinforcement works in dog training. Negative reinforcement involves removing an unpleasant stimulus when the desired behavior is performed. In this context, the pressure from the leash can be considered an unpleasant stimulus. When a dog responds correctly to the handler's cues, the handler can release the pressure on the leash, thereby reinforcing the desired behavior.

This process teaches the dog that the absence of pressure is a reward for responding appropriately. Consequently, the dog learns to perform the behavior without relying on the leash's pressure over time, as it understands that a correct response leads to a more pleasant, pressure-free experience.

Positive reinforcement, on the other hand, refers to adding a pleasant stimulus to increase desired behaviors, such as giving treats or praise. While it's also effective for training, it doesn't specifically address the aspect of leash pressure in the context presented.

Negative punishment entails removing a positive stimulus to decrease a behavior, while positive punishment involves adding an unpleasant stimulus to discourage a behavior. Neither of these concepts effectively relates to helping a dog learn to respond to cues without leash pressure, making negative reinforcement the appropriate choice in this scenario.
