My family and I have an upcoming vacation, traveling by car. The trip is going to be about 12-13 hours, and we plan on rotating drivers so we don't have to stop overnight.
We will be taking my parents' 4-year old boxer with us because he is such a handful for dogsitters and does not do well in the kennel. He is normally a very good dog in the car, and does not move around much, but for the safety and comfortable of everyone, he will be riding in his crate in the tailgate area of the SUV.
We plan to stop every 3-4 hours to allow him to exercise and relieve himself but we are worried if that is too little. We are also concerned about water in a moving vehicle. Should we be stopping more often to allow him to drink?
