Does your dog like to stand on the center console when you are driving, or sit in the middle seat so he can see where you are going? Mine does too! That was fine until one day when I had to brake hard he came flying into the dashboard, changed my radio stations and knocked the gear shift in neutral.
Does your dog like to stick his head out the window when you are driving? So does mine! Until one day, he saw a cat in the car next to us at a red light and tried to jump out the car.
Now he is always leashed up with our Max and Neo seat belt leash. This keeps him in the back seat where he belongs!
