I am a little late, but I had to reply!
I lovingly call my schnauzer, SirFartsAlot. Let's just say that the dog's got some stinky going on. Though it's funny, when you hear a "pphht", it's not stinky, it's the silent ones that are deadly.
First time he let one pass, and I heard it. I looked at him and he looked at me with a look of 'why did you do that?". Blamin me for it!
Though, he turned 10 on the 15th, and we had gone out to dinner to celebrate DH's birthday. We had a huge porterhouse steak and brought home the bone for the dog. Let's just say that he passed Poterhouse Steak Farts for about three days and they were AWFUL!
