I appreciate your kind thoughts very much, Linda. I hope other dog lovers will not make the mistake I did of letting their beloved dog ride in the front seat of the car. Of course, Sadie leaped from the back seat to the front on her own, as she often did, from excitement when we were getting near a favorite walking place. But instead of thinking that was cute, I should have taught her not to do that, or I should have pulled over and made her get back in the back. Granted, she might have dislocated her hip even if she had been in the backseat because of my having to put on the brakes suddenly to avoid the idiot driving the pickup. But she would have had a better chance, esp if I had thought to put some padding behind the front seat for her.
Sadie always had loved to ride in the car. She's gone with us on long trips, such as 7 hours to the beach, never complaining, always wanting to be with us. Despite the accident, she has no fear of being in the car. I've had to lift her into the backseat several times for trips to the vet since the accident. Hopefully, there will be fun trips for her in the future, but with her in the backseat and some padding back there. I have trouble believing there is a seat belt that would comfortably contain an exuberant lab but I will certainly look into it.
Thanks again for your kind and thoughtful words.
