At the moment, no one.
I had Meeko for a short while, but then he got killed by a random murderous High Elf bastard.
I'm in Volunruud as I type this, and these ancient Nord tombs are scary with higher level Draugr lurking behind every corner. I'm getting a follower as soon as I get back to Whiterun.
Meeko is a nice dog, but he isnt a war dog, I alway try to keep out of battles with him around.
I wonder why Faendal likes the stormcloaks/Nords, any time I attack one he attacks me. Over that I prefer Sven, outfit him with some iron, then kill him in the wilds, as I do with all my first followers as a sacrafice to Hermaeus Mora.
With My, Esbern, Delphine, Barbas, shadowmere, Lydia, two permanent flame atronache's, Odahving and spectral assasin. I gained 2 more followers, how many can we have
as barbas is a quest follower, I gained Vigilance, and also serana.
11 followers
Though, I dont actually want them there, its abit, overkill, so I did the quest and got rid of delphine and esbern, Barbas and serana. Wont use Odahving(He's useless anyway, takes ages to come) and spectral assassin. ah but im still left with my Atronache's,dog and lydia, whom I will kill for someone else.
