At the moment I've got over 100 prisoners in 3 different holding cells - so it gets pretty crowded as they transition through their regime. I've found that any time there is a fight and a dog is near, he will continue to attack the prisoner after he's been subdued. If I don't move the handler out of the way and break the command, the dog ends up eating the prisoner to death. It's extremely frustrating when I have to click-drag across the mass of raging prisoners & guards and keep moving my guards to different locations just to stop the dogs from killing prisoners.
I've had a quick look through the forum but haven't found anyone reporting this as a specific issue - it's been mentioned here and there, but for me it is really impacting on the playability of the game.
If this is a known bug, please let me know. If I should add it to Mantis, I'll happily do so. If it's how the game is intended to be, well I'll keep on with my click-drag button mashing!

LOVE PA though!
