Receiving the mark is an act of the will,your dog did not have a choice so he's good. Speaking of willingly taking the mark, this law plays right into it, you would have to choose to take it. I figure they (Companies or Gov) will add incentives for taking the CHIP, at least at first. Eventually without it you won't be able to buy food or be able to pay your bills, or collect a paycheck SEMPER FI
