Oh Dear
Having done film work with my dogs, and read about the temperament of Pollux, I cannot see how the two are going to Mix.
I truly hope the film/TV industry in the US is different in its attitudes to animals than it is over here.
....you missed the bad news - which states that Pollux has developed such bond, he will not work for anyone else. He is going to cope well with being handed to strange actors then isn't he!
