My dog is a 140lb wolf dog that refuses to get out of the car after a ride. He loves kicking it in the car! Sitting in a car, guarding his master’s property is a pretty normal thing for a dog to do. It’s not torture by any means. There are, in fact, 24 hours in a day. 3 hours in the car leaves… 21 hours of playing time! That’s quite sufficient if you ask me. So why don’t you buy a dog & make it play non-stop for 21 hours, & see if it wouldn’t mind sitting in a car. Then, stop wasting your time freaking out about any dog in the world who might, God forbid, go through any amount of slight discomfort in his doggie life.
