Make sure not to leave his cooling pad down unless he's supervised. Not long ago we had a bully here that ate one and passed away even though it was suppose to be non-toxic: http://www.englishbulldognews.com/fo...hlight=cooling
Aubie loves to be cool. She is wound up in the car until we get going and then she lays down and goes to sleep. I think once he gets used to it, he will calm down and be fine. When it comes to barking in the crate, we bought a crate cover with Aubie and put it on to make it dark. She learned quickly to just lay down and be quiet or go to sleep because the way we situated the crate she couldn't see us. Maybe something to try?
