No, you cannot Dead Thrall animals. You can use up to Dread Zombie on animals, which can be fun. You can only use Dead Thrall on humanoids. The spell even reads...
"Reanimate a dead body permanently to fight for you. Only works on people"
So I am guessing you did not play this build before posting? Not a big deal for me, it is just hard to sell something you haven't played...
