I took Leo out after his second set of shots. There is so much conflicting info out there about when they are protected, how many shots they really need, etc. I dont blame you for being cautious with him but we didnt have any problems taking Leo out after two sets, even to places with a lot of doggy traffic. You made it just in time to get him out a bit before it starts snowing and they dont want anything to do with outside until spring lol.
