I am currently watching a Watts the Safeword Vid so that hits close to home. They do a great job explaining. Also i agree with it being quite varied. In general Kink is always something rlly personal and mostly cannot be strictly defined
It’s a different feeling in the dynamic. It can be very literal with the person behaving like an animal but also can have them have only animalistic qualities like the want to make the owner happy that dogs have. Also for me i just like to be treated the way an owner treats his animal
