Sorry if I misunderstood. My apologies.
Thought just occurred to me that if the dogs are so valuable and are that tame/well behaved, just call them over, tie/lock them up and call the sheriff or animal control. If the owners show up first, tell them they can't come on the ground and have to wait to talk to LEO's/Animal Control/Game Warden. Keep the dogs watered and in the shade until they are picked up. A few fines would probably get the offending hunters to take better care. Of course, the other thought is once someone starts hunting on land without permission, (depending on state laws as Newbury points out) that might be poaching. The state might take their dogs, their transmitters, their trucks. They better watch their attitude.
Dogs running through during or just before hunting season would bother me. The only year I got zero during deer season is when my neighbor let his pack run. Still, I didn't yell at anyone. It was just a firm but polite keep the critters off my ground. One told me his dogs didn't run game. Just then a big doe bolts across the field in mid-day. A few seconds later, here come his dogs. I looked at him and with a smile said "Don't run game, eh?" As I said, he fenced his place pretty securely a few months later, problem solved.
