My favorite thing about dog ownership is how you'll get a dog that loves squeaky toys, and she'll run around the house chewing on it all SQUEAKYSQUEAKYSQUEAKYSQUEAKYSQUEAKYSQUEAK and everybody goes "ZOMG, that's so cute, look at her with that toy!" and somehow totally separating themselves from the fact that the squeaking is meant to simulate a prey animal in distress, and the animal relishing in that sound can snap your arm bones in half with her jaws.
And that's an animal that actually loves its human.
