Okay, laughing at Nanook letting out a long squeeky blow while sitting there.
Shadow did that one day when we were in obedience class. It was the final test and everyone had to perform solo, as I put her in her sit/stay in the gym she let rip a really long noisy fart. Everyone was laughing and I was saying "It wasn't me!!!" You gotta love gassy dogs. Glad to read he seems so much better though.
