how long to dehumanize a person into thinking and acting as a dog, assume complete immersion in the new role

Dehumanizing a person to the extent that they think and act like a dog raises significant ethical concerns and is not a feasible or appropriate goal. Human beings possess complex cognitive abilities and social emotions that cannot be simply erased or transformed. Any attempts to impose such a role could lead to severe psychological trauma and harm. Role-playing or immersion in a character, like a dog, might be explored in controlled environments, such as acting or therapy, but it is essential to approach such activities with respect for individual autonomy and mental health. It's crucial to prioritize consent, well-being, and the ethical implications of any form of role immersion. If you have other questions or a different scenario in mind, feel free to share!
