Correct me if I'm wrong, but you can get a vvps to turn the temps higher or lower than standard. If you only want to lower the temps and want a cheap quick fix you can order a $6 light dimmer.
So my first pup should be arriving Tuesday (damn holidays) and I am so excited! Unfortunately it just clicked in my head that I might not be able to use my dog with my zob because it is stemless :/ Hopefully my dog is skinny enough to work with it, if not I might have an aromadog for a few days...
