Did ya blame it on the dog!!! I use too do that to Ruby when my wife was in the room with us!! she got to when I farted she would just get up and leave the room!! (ruby that is) and on her way out she would stop and look back at me!! the look on her face was priceless!!!
Leo tries to smell my butt after I fart...It's a dead giveaway, so I can't blame it on him anymore unless he's sleeping.
Honestly though, the majority of the time it's him; he's the fartingest dog I've ever owned.
