Having dogs with you limit what you can do, and how long you can leave them in the rv. If they are not used to it, they tend to bark the entire time you are gone, which can lead to problems with the neighbors. Im sure it stresses out the animal as well. Only you can decide if you are willing to do what it takes to have a dog. Myself personally, I wont get an animal, because I want the flexibility to change my mind at any time, and not be committed to have to return to the rv every four or five hours. I travel with friends who have dogs. I see the problems it creates, but people who love their dogs, love their dogs, and are willing to sacrifice certain things for their pets. Many rv parks don't allow dogs over 80 lbs. For ease of travelling and size, I would try to pick a breed under that size, and not on a banned list.
