you have had your question answered about 5 times TAKE YOUR DOGS HOME FIRST, THEN GO BACK FOR THE DEER WITHOUT THEM
read the question again!! am i breaking the law??
well technically no but you no deer are on the land, you no your dogs are capable of killing them, your armed with a shotgun not a rifle so it would be against you to prove otherwise just carry on regardless and worry about it when the time comes but one thing i would say is to take the dogs home and go back for the deer later
