Words with positive associations should be chosen for programming the buttons because they are linked to experiences or items your pet enjoys, such as 'Treat,' 'Play,' or 'Walk.' This positive reinforcement motivates pets to engage with the training process, as they anticipate a rewarding outcome upon using the button. Positive associations enhance learning by making the interaction enjoyable and memorable for the pet, increasing the likelihood of consistent and enthusiastic participation in the training, and using talking paw buttons.
