Wyo, have to respectfully disagree on all parts of your response. The SPCA does excellent work. It would appear to me that if you had been anywhere in eyesight, you would have known that a complaint had been called in, they responded and found things unacceptable. Possibly illegal, depending on where this occurred. Maybe things are different in WY, but I've seen the results of dogs being ejected from trucks after a sudden stop, defensive swerve, whatever and it's not good. I'm sorry you feel that your dog was treated badly, but you should have been where you could at the very least keep an eye on him and you would have avoided this. Sorry about the expensive bill, but consider it a lesson learned and avoid it in the future. Hope your dog is fully recovered and getting lots of tummy rubs.
