For the last 7 years we have driven from northern Wisconsin to our properties in The Villages 3 X's a year
with our 2 dogs. In those 7 years we never had one negative experience with our dogs, they love that trip !
Google pet-friendly motels with dog park areas nearby on your route, also all the rest stops have pet exercise areas to accommodate travelers. Make sure you carry a current vaccination record of your dog in the glove box, and most important, attach an ID tag to the collar of your dog.
FYI~ A dog can sense it's owners anxieties, so relax and safe travels.
