i haven't done it in a while but on my days off i use to get
up at 5am or 6am. i drove the dog to one of his play/potty
areas. then i bought a bottle of spring water and were off to nowhere.
i would drive around with the music playing while my dog was sleeping.
i would drive around 2 or 3 hours. my dog laid in his hammock
and slept most of the time (great riding partner, lol).
we have a 7 hour drive coming up. i think stopping for a break
every 2 hours should be fine. i'm giving myself an extra 2 or 3 hours
to reach our destination. i found a B&B that's dog friendly.
enjoy your trip and don't forget about the doggy treats.
