If you start them early, dogs can adapt to anything!
Gee, how bout dogs that ride on motorcycles, and service dogs that do it all.
I think that a mid sized dog would make things easier, but that is a personal decision.
So far in my experience, traveling with dogs, it's no problem. If possible ,just call ahead and most motels have rooms set aside for those traveling with their pets
Think it over and best of luck!
There is no love like that given by a dog
BTW....I can't wait to see your baby pictures
