If all dogs came from wolves, how did we get so many different breeds etc?

Like how do we have pugs and Aussies and all of that jazz? Might be a dumb question but I would love to know!

Selective breeding.

In the beginning we didn't have "dogs", we had wolves that didn't attack us, and protected us, in exchange for warmth & food. With time, as humans spread around the planet, we started setting them to different tasks like guarding or hunting. And each generation *we* chose which dog could sire offspring, selecting those that had favorable traits, and/or were better accustomed to a certain climate.

And much later people got pretty much insane & wanted dogs that were fashionable, which is why we get breeds that wouldn't survive even 5 minutes without the comforts modern humans provide.
