We are not fulltimers yet, but do quite a bit of camping with our travel trailer during spring, summer, and fall. We travel with two Dobermans. They were the big reason we bought a trailer again, as we hated leaving them behind. Ours are quiet in the trailer when we leave them. We have never had a complaint, and we wait when we pull out to make sure they are quiet, and check when we get back to make sure they are quiet. We leave them 'Kong' toys stuffed with treats and peanut butter to work on while we are gone. We make sure to always pick up after them, and make sure they are not nuisances to anyone. With our breed, we needed to commit to long walks so they could get their exercise. A smaller breed will not require as much exercise, and can usually be exercised in the trailer if there is enough length to roll a ball and play fetch. Different breeds have different energy levels, and that does not depend on size. Some very large dogs are much more laid back than some small dogs. Consider grooming. If it is raining outside, can you deal with your poodle coming back into the RV with mud on its coat? Our breed is 'wash and wear', a quick wipe down and they are clean again. Consider how much fur/hair you can put up with in the RV. Our breed does not shed much, and the fur that is dropped goes to the floor and does not 'float' in the air. The hardest part for us is when the weather is too hot to take them in the truck with us for outings from the campground. We try to schedule early morning and evening outings if we can, so they can comfortably stay in the truck. But it does eliminate some of the stuff I would like to do, like browsing in shops. Hubby of course hates shopping, so sometimes he just stays 'home' with the dogs. : ) Also, some breeds are just barkier than others. Dobermans generally bark only when there is reason to bark. We feel quite safe with them! There is a lot to consider. Take your time to make your decision and research a lot. Talk to breeders. It would be awful to get a dog and then have to give it up.
