@Shaye's:
When we go anywhere in the car or the SUV with her, we wrap her leash around the back seat giving her some leeway but not much, and put her in there with a bed (not the one she sleeps in at night, a little round white thing) and a toy and a bone for puppies that she can eat, but very slowly.
This is really unsafe for her. If you are in a car accident the majority of the force is going to be on her neck. If you are not going to crate her in the car then at least check out the threads about Doggie Seatbelts. There are some good seatbelt harnesses that are designed not only to restrain but also spread the force of impact in an accident.
As for crate training, you may want to check out the DVD Crate Games which has some great recommendations about how to make the crate a place that your dog wants to be and has positive associations with. http://www.dogwise.com/itemdetails.cfm?ID=DTA287
As has been stated, crate training is not just for housebreaking. It gives you a safe place for your dog during travel both in the car and when you stay at hotel, relatives, etc so that when you can not supervise your dog is safe. It also makes recovery from surgery much easier because the dog can relax in its crate and you don't have to worry about it doing things that it is not supposed to.
