Owning a dog is a full-time commitment-- when you adopt a dog, you're adding another member to your family.  So when it comes time to start shopping for your next car, you might find yourself with more to consider than usual.  There are lots of details that are worth paying extra attention to on behalf of your canine friend.  Although lots of dogs like to ride up front with their heads sticking out the window, it's much safer for them to ride in back.  obviously the amount of space you need will depend on the size of dog.  Small to medium dogs will be very comfortable in the small to mid-size suv's and crossover's which usually have around 25 feet of cubic space, and the larger dogs will need more room ,so the full size that have on average around 70 feet of cubic space would be more adequate.
