I have never had a Dobie but have camped with our 2 German Shepherds. I never ran into any breed restrictions with them per se. I did ask when making the reservation if it would be a problem to bring them. If nothing else, they were like a novelty because whenever we would have them outside and people would walk by everyone would stop and ask us if they could pet them. Even a park ranger at a SP stopped by our TT just to see them and comment how much he appreciated us having them under control. We now have a 9 month old German Shepherd puppy that we just started camping with. She is super social - almost too social but I'd rather have her that way than the other extreme. Good luck!
