Bandit has twice alerted me with a very low growl when he was in his day-time crate, while I was sitting on the couch watching TV (same room). I took him outside and even though he took forever to sniff out that perfect place, he did go pee!
It's funny, when I have "school" with the five of them, Bandit picks tricks up very fast. He can sit, sit up pretty (like he's begging) shake (paw) and wave bye-bye, you'd think he could get the potty thing
down a little faster, go figure... Here's Bandit (left) and three of the others waiting for the next command at school.
