Dogs are hunters and know when deer start to move, they don't happen by your stand at prime time just by chance!

Scrub - C'mon man, really. Dogs dont need to sit and wait for deer to move, they can smell them. They will know where the deer are at without having to see them.

I'm getting the picture that we are talking different scenerios here

#1- Hunter is sittng in stand, sees dog trot by sniffing and peeing ears a floppin' as one usually does, two minutes later the owner walks by on the same trail. an hour goes by and hunter sees the same dog trot by going the opposite way sniffing and peeing and turns up another trail. 5 minutes later owner walks by and heads up the same trail following dog. another hour passes, dog trots by sniffing and peeing and right behind it is the owner and they disappear down the original trial they came up. Now its obvious the owner has his dog out for a walk. is the hunter going to blast the dog in the chest? probably not. now i know someone is going to say, well the idiot shouldnt be walking his dog in the woods during hunting season. this is true, but some people, god forbid, dont hunt, therefore having no idea the season has arrived. i dont follow tennis, so i would have no idea when wembolton is, or even how to spell it. I know thats a bad analogy, but it works.

#2- a pack of howling crazed starving dogs crashing through the bushes all morning and afternoon long trying to find food, the owner probably has no idea wher the dog, no does he care if the dog ever returns.
