I have made several animal companions, and given them entries in the DialogueFollower quest for all appropriate things they should be able to do. The problem is, to get them to follow me I used the WEDogFollower script (which basically says, if you don't have an animal companion, this thing follows you. No dialogue included, which I don't like.) and if you use that seemingly the DismissFollower function from the DialogueFollower script doesn't function on them. It will say that the follower has left your service, but it will continue to follow you around.
So, I removed the WEDogFollowerScript, and made a new quest called PKRecruit, which has just one dialogue topic. Basically it just says ", I choose you!" (the whole akSpeaker thing did not work, so if you know how to make it so that it displays the name of the actor being spoken to I'd appreciate it) with conditions that you have to be one of the animal follower actors to have this dialogue option.
Then it runs this script:

akSpeaker.SetFactionRank(PlayerPotentialAnimalFollower, -1)
akSpeaker.SetFactionRank(PlayerFollowerFaction, 0)

In order to make it so the animal follows you around. But it doesn't work. Does anyone know what I should be scripting to make it a follower that I can later dismiss?
