How old is he?
Is "Dad" and experienced decoy? Worked lots of dogs?
I have found that my dogs will not bite me the same way that they bite someone else.
Never let the dog win just for "grabbing it." The dog only gets the tug for full hard bites, nothing else. You will wind up with a lazy dog that has learned it doesn't have to bite full and hard to win. He is also not going to fight "Dad." At your dogs age, calm is ok.
