I can't help you with trainers in your area, but I'll put my two cents in on the outdoor kennels. I have several german shorthairs of which one is solid liver and one is black. I live in southcentral illinois which gets very hot and humid during the summer. My dogs do just fine as long as shade is provided and sufficient water is available. We havea golden retriever who is a pet and prefers a shade tree to climate control. I also have several friends who raise/train labs in the area with outdoor kennels. Good luck with your search for a trainer, but I'd say if you liked the guy and he has good references a few weeks of the lab being a little less pampered won't hurt him.
