I have two that I can sneak in. They love to be in carriers and are SO well behaved. I have snuck them into the mall many times...but then, our mall is not as bad as some. But...I can close their stroller and they just cuddle up and sleep.
I always take them to the dog show because they sit in their stroller and never jump out...and that is all day long for four days.
Most of mine would be out in the agility ring by themselves trying to compete.

Guess I am not much of a trainer.
