I boarded a cross-country flight a while back and watched them loading luggage into the hold, put a dog in a crate up the moving ramp and one guy knock the water bottle upside-down so there was no way the dog could drink. The guy looked at what he'd done and then just ignored it. I alerted the flight attendant to this. She seemed bothered, wandered off and came back later and told me it was fine, she'd told them about it. I had my doubts.
