A flip to this - in the interest of balance: My downstairs neighbour has bought a Pomeranian. I've had a look and apparently this is about the least suitable dog to leave alone in a flat... they hate it and go mental. He obviously didn't consider this and since his wife started going to work, the little furball has been mounting a sustained campaign of wolf howls and yaps all day. My wife and I often work from home and it's such a downer.
Anyway - we were chatting with him about some other house related stuff and just generally hanging out the other day. I mentioned the problem with the dog and he seemed genuinely concerned about it. Said he regretted getting it and had already tried to give it to his Mum. It's been a bit better since then (dunno what he's done to calm the dog down)... but to be honest - just knowing he's sympathetic and trying to sort it more than halves the stress as far as I'm concerned.
