I think everyone has mixed feelings about this issue, but here's where I stand.

I'm okay with dogs riding around loose in the back of a pick-up truck IF the person is just driving down back roads and not traveling too far.

On my way home today, I was behind a truck on Sam Houston Toll Way with a dog completely loose in the back of his truck. It made me sick to my stomach! It was a four-door truck, so I know they could have found room to let the dog sit in there. It just disgusted me and I couldn't wait to get around the guy so I didn't have to look at the poor dog.
