Is Stewie Griffin gay for the family dog Brian?

Answer 1

Yes; little Stewie is in fact gay for everyone (if that makes sense). Seth McFarlane said in a recent interview that Stewie is definitely homosexual.

Maybe this can help:

Seth MacFarlane said:

"We decided it's better to keep it vague, which makes more sense because he's a 1-year-old. Ultimately, Stewie will be gay or a very unhappy repressed heterosexual [which still means he's homosexual]. It also explains why he's so hellbent on killing and taking over the world: He has a lot of aggression, which comes from confusion and uncertainty about his orientation."

And he told The Advocate:

"He originally began as this diabolical villain, but then we delved into the idea of his confused sexuality. We all feel that Stewie is almost certainly gay, and he's in the process of figuring it out for himself. We haven't ever really locked into it because we get a lot of good jokes from both sides, but we treat him oftentimes as if we were writing a gay character."

Answer 2

Yes, Brian is also the only one that can actually understand Stewie and carry conversation with him.

Answer 3

Because everyone can understand Stewie, but because he's a baby he's not taken seriously unless the scene requires people to respond to what Stewie says.
