We use the COE park system. There is never any problems with my dog. I also use this as an opportunity to educate the public by showing how well behaved a Rottie can be. I cant take him for a single walk without at least one person wanting to pet him. I just love seeing the look on parents face when a group of kids run up to him and want to pet him. I just tell them one at a time so they dont scare him.
Now, on to the real problem with RVing with large dogs, THE SLOBBER!!!! My god the slobber!!!! We have to wipe down everything from waist level down and shampoo the carpets after every camping trip.
