Not sure. I mean I had a couple of dogs for a couple of years in the 00's - one admittedly was a good liddle fella - adorable, the other a right little twat, properly obnoxious. And he had some erectile problems - he used to stand there motionless in a strange catatonic state for up to an hour at a time with an unshakeable erection, staring at you with his hollow little eyes. I guess at least during that time he wasn't being obnoxious, however it's hard to focus on the TV when there's a little dog sitting in front of you proudly displaying his pulsing meat stick. Anyway, he's dead now.
