There already are my dude. Plenty of dog breeds that are just what I like in a dog; goofy, lovely, loyal but not territorial/protective and nothing that could seriously hurt anyone. The other characteristics comes down to subjective preferred traits and, for example, whether you're a first time owner or experienced with raising and socialising dogs.

But you can't ignore instinct. And some have instinct that's just not compatible with your personal live. Ie. don't get a shepherd if you live in an apartment in a city.

And some have instinct that is not compatible to keep as pets.
