The next test we're doing is a hoodie from @maisontiet and I really wanted to run the test on volunteers wearing it. But before we did that we wanted to make sure the dogs would alert on people, something they've been trained to ignore during a search. That has taken a bit of time to train and it isn't 100% yet. Here we have Ender alerting... by muzzle punching and nibbling my crotch.
