My father and I had a dog with us as we scouted all of last fall except for the last 2-3 weeks before the season. Having your dog with you really won't make much of a difference because the deer movement won't change because of it. It is more likely to change because of your presence than your dogs.

We've brought dogs along to scout with in the fall for so many years now, I can't imagine not having one with us in the woods. It's good exercise for all of us.
