i think you need a gradual approach instead of the ole force her into the car approach. i realize that she will have need to go to the vet and such but until then here is what i suggest. take her outside near the car and just walk her around it. lavishly giving treats when she is calm. you might do this 2-3 times a day for a few minutes each time and give her lots of praise and treats/toys. when she is comfortable with that i would open the back/door of the suburban and repeat the process. just go as close as is comfy for her (no signs of stress) lots of treats and praise. then as she is able to get closer and closer maybe just ask her to stand in the back of the truck (no crate yet). gradually work up to getting into the crate (door open) and not going anywhere. lots of good salient treats (like chicken or hot dog -- something delicious that she doesn't get on a regular basis -- special treats that she only gets for this activity). remember take it slow. hopefully you will be able to work up to her getting in the crate close door -- go nowhere. then try driving to the end of the driveway. then to the end of the street, etc. it will take time and patience but hopefully she will enjoy her rides again. remember to go at heidi's pace. forcing her into a stressful situation will likely only exacerbate the problem.
