Again, not knowing all the details or the dog, I am guessing the dog is really tense on the mill. Watch the muscles, I am guessing they are 'flexed' while running. If so, the dog is just not comfortable being off the ground, which is normal.
I have one that is not an enthusiastic mill worker. She is almost 'freaked' and 'tense'. If she hears another dog bark or sees a dog she will run the mill. Not all out, but almost power stepping. I shorten the sessions because she is 'flexed' and with that said, straining thru every step. Anything over a few minutes and she has a slight tremble, especially in her front legs. It lasts only a minute or so after she is on the ground/floor.
This is just a guess as I have never did any sort of medical testing or veterinarian checking on this female. Just an observation. EWO
