I just had to get this off my chest:
Dog owners - leave your dogs home when you go out in your vehicle. I doubt very much that dogs want to stay cooped up in your vehicle, or tied up to a post outside a store or whatever. Especially when it's very hot outside. Another thing that bugs me is dogs in the back of pickup trucks. They're flailing around as you careen around corners. It's a wonder they don't go flying off the truck (or maybe sometimes they do). Sometimes I see this when it's freezing cold and the poor barker is trying to stay warm. You wouldn't do this to a child, so why is it OK for a dog (or any other pet)?
I just don't get it.
