Be consistent in how you handle your dog. When mine starts to get out too far, I'll holler out woe, or if I want him to get out a little bit further I'll say "look for him". Handle squirrel dogs similar to the way that quail dogs are handled. Consistency leads to control ! First and foremost hunt in a safe area where you have enough acreage away from hazardous areas such as those previously mentioned. I can't tell you how many times I has about to call my dog back in when he made a large circle and then came back and slammed a squirrel to the tree closer to me. Sometimes a dog needs more room to work and drift a track based on the conditions. Remember that every time you go hunting that you are also going " dog handling" and that as your new dog learns to hunt that you are also learning how your dog hunts and what your dog responds to in terms of handling.
