Nowhere I've camped has it stated you cannot leave your dogs unattended in my camper. I'm sure some places are like that but I've not been to them There have been sites where it states you cannot leave them unattended outside. 
But, Oh my gosh call the news, we do leave our dogs unattended on occasion. And as of this day, we have never been complained on about our dogs. It's just like leaving our dogs at home. Yep, they don't go to work with us so they have to stay.
 
I'm not an idiot and I know dogs bark but you train them and they do just fine. It is not feasible to take them absolutely everywhere we go. We just don't think taking our dogs into the stores and restaurants is proper. And we're great dog owners. I would love to be one of my dogs. They have the best life ever. 
Now come on with how we're horrible people and have no respect for others. I'll just laugh.
