The most likely thing is that some of the Dialogue Options (Follow Me, Dismiss and so on) for meeko use the RACE.
So if you have changed the race, any that do use it will no longer work.
So, you would have to find and change those conditions.
HOWEVER: It would be better to create your own "custom" Huskie Follower, rather than editting anything vanilla.
If your scripting is up to it, there is help on how to do just that ...
If you scroll down to posts #16 & #19 in http://www.gamesas.com/topic/1349193-wip-an-unexpected-companion/, it outlines the basics of how you would start to set up Custom Followers (you don't need to use any of the vanilla quests or dialogue etc at all)
