It's terrible what some people think of our little dogs! Calling them "rats", "want to be dogs", (like you said), they are just too stubborn to realize how amazing our little "rats" can be. They also have never experienced their own "rat" to realize they can do just as much as those big dogs can plus more. People like that you have to ignore.
Your babies did look like they had fun! Hopefully they ignored those nasty people.
