I'm really not sure how Duncan feels about riding in the car....I don't like having him in it unfortunately!! I have a really small car, a Honda Civic 2 door and as you may know, Duncan is a really big dog so it doesn't work too well. First of all, he has to stand between the seats and I can't see out the back window or the side window. I roll the passenger side window down so he can stick his head out but he has broken the arm rest from standing on it! And in the summer, I can't let him hang out the window because he will bite anyone that comes too close! Once, we were in a bad part of town and this man walked right up to my car at a stoplight, even though Duncan was hanging out the window. Duncan but the man in the arm and I drove away... I felt bad but I'm sure from the part of town we were in, the time of day and the way the man was acting that he was up to no good.....
Also, he HATES bicycles, absolutely HATES them so if we see one, he barks like crazy at it and tries to attack it through the car window. He also does this for squirrels, other dogs, cats, motorcycles.....etc. So riding in the car with him is an adventure that I don't look forward too. I need an SUV so I can keep him in the back. I've tried everything to get him to behave but nothing works. It's hard to train your dog when you're driving too.
It's too bad because I love to take him to different parks and stuff to play...I do it anyway and just deal with his strange behavior
