I havemy deerdog penon my family'sland and the deer walk within 75 yards of the pen. I have rode out there and a doe and yearling were feeding around the pen and the dogs had winded them and could see them. They were goign crazy, barking and trying to jump the fence; didn't bother the deer at all. We have two stands across the creek that intersects the parcels that are maybe 100 & 200 yards from the dogpen. I have killed bucks at both of them and they don't even acknowledge the dogs barking while they are so close to them. Short answer- no it won't bother them.
