My housemate has been doing dog sitting. It's greatly raised my appreciation for properly trained dogs. Unfortunately, the one she's got down there right now is not one of those and is EXTREMELY ANNOYING.
Turns out the owner lied, said the dog was well behaved, but it has severe separation anxiety and isn't crate trained, so it's been barking constantly since being dropped off and is peeing everywhere. A pox on irresponsible dog owners everywhere!
(she's working with the dog sitting company to get it out of here.)
