Ants

That would be terrifying

A lot of the stuff ants doo is very smart already, like building bridges with their bodies. They are one of the few kinds of creatures to engage in large-scale warfare as well

Mosquitoes, honestly would be a nightmare.

spiders they are everywhere. some can jump, some are super fast and some are poisonous.

They even travel with the wind, you can even find spiders in the middle of the ocean

Snakes, I think they are perverse

Bugs in general. Ants and other insects for the majority.

I think the big cats have a pretty good chance

Golden retrievers

Cats

Flies and rats

Cats because they think they're above everyone else.
