However in the games, there a quite a lot of Pokémon species that are in no way smarter than regular real-life animals.
Just because you can give them instructions during battle doesn't mean they understand human speech, it's like giving an order to a dog : it doesn't understand or recognize any meaning in the word, it's just memorizing and associating a string of sounds with a certain action.
