I pulled up to a CEO's house with a gang of three escaped convicts, who were wearing clothes of the same fashion as the servants around. They managed to carefully and stealthily open the locked doors towards the delicious safe in there somewhere. I evaded detection by any of the servants or guards. However, I walked into a guard dog. It smelt straight through my disguise and started barking to alert the guards. I tried to convince it we were servants by scratching it behind the ears and whatnot, but it wouldn't have any of it.
Of course, the team leader pulled his concealed pistol and shot it in the body until it stopped moving. Still though, the dog had learned so much in its time with us that it learned to speak with its final breaths.
"Better dead than liberal"... okay, could have said something nicer but still.
