I've had dogs all my life and can not remember ever bringing one to a club field. I did occasionally take a dog to a sod farm where I was the only one flying, but it was always a distraction.

Dogs in the shop are a problem too. They don't normally wear safety glasses so flying particles can be a hazard. I fly out my front yard at the moment and the new puppy Stormy is rather curious about everything including starting the plane, paper towels, and the plane on the runway. I feel I am taking a big risk letting him roam free when I fly, and I sometimes lock him in the house so I can focus on flying. Dogs and RC airplanes just do not mix well. If you do put them together, you are increasing risk in some area. You just might not know where until the line is crossed.
