As the title says. Been planning to pick one up for my bosmer stealth archer. I really have no interest in the two legged variety. Has anyone actually found our canine buddy yet?

I'd like this answer. I don't care for humanoid companions... always went with the dog in FO.

Yes, a Hand-On's Journalist found one. He was the journalist that received that image with a Dunmer Female alongside her Dog Companion.
(A Dog Companion that died after a misplaced Fire Spell if I remember that preview well)

Yes its confirmed. What Im not sure is whether the dog counts as your single companion, or if you can have the dog + say, Lydia or whowever.

I can already see myself getting too attached to my dog companion. Hopefully they're invincible.
