When you have an animal in your story they can never be just animals. They have to be smarter than normal and act outside of what would be normal for their species.
Yep! Even baby animals, like puppies, never need to be trained to fetch objects, spy on the enemy, or not pee on the rug. Who has time for that?
And everyone must love the animal friend. Because who doesn't love adorable, smart creatures? Except villains. Villains hate everything. The only pets a villain can have is something just as evil and ugly as them, like reptiles or insects, but not dragons. Those are too cool. And the villain's pet must always be defeated by the hero's pet, even if it's a bunny versus an alligator. Have the bunny suddenly develop powers in order to win if you have to, but make sure they do fight and win!
