Food.
Humans are easy to train with food. It only took me a couple of hours to train them, although sometimes they eat some very tasty smelling food and do not share. I am working on this.
If you were to get your own human then training them with food is fun. Some humans are slow to learn so additional whining, barking or running around in protest is needed. If all else fails you may have to resort to feeding yourself as they do tend to leave snacks around all of the time. They somestimes even make a game of it by putting food at higher levels or even hiding in cupboards. They pretend theay are shocked or annoyed, but if they didn't want us to eat the food they would have not left it in reach :whistle:
