If you think the public outcry - such as it was - had anything to do with Brian's return from death on "Family Guy," you're flat-out wrong.
The animation process takes months. Episodes are in production nine months to a year before they air. So, clearly, bringing the cartoon dog back from the dead was always in the plans.
Which makes the whole thing even more cynical and manipulative than it would have been had Brian stayed dead.
To make a long, rather stupid story short, young Stewie encountered a time-traveling version of himself, grabbed his backpack time machine, jumped back in time and prevented Brian from getting hit by a car and killed.<
