I've got a trail cam set up at the moment not 30 yards from my dogs' kennel. It's been a learning process for me, but the deer are there, despite the fact that my younger one has peed on every tree within 200 yards of the house. I agree in that I think they get used to it. - It certainly isn't helping anything, but is just a part of life that we hunters have to get used to and adjust to. Good luck and keep us posted.
