Hi Chad
We have 3 large dogs, and everytime we move a deer from another farm in we gradually introduce the dogs on a leash over about a 2 week period. We start off by keeping them at a pretty good distance and slowly working them a little closer every day. If you watch the body language of the deer you can tell when they are getting nervous and we back away. I think the most important thing is the new deer watch and see the reaction of the other deer. We have 6 deer that came from other farms and have introduced them all to our dogs. But let a strange dog show up and all he** breaks out.
