When don't they?! They are so FUNNY... We once had a 17yr. old Bassett Hound named Archibald who had gas and we had a dinner party in our small apartment...Everybody left really quick holding their noses.
...... Then there was Digby the Tortoise & The Crows, who when I was little my parents were studying with the Jehovah's Witness and Digby walked into the house followed by our Crow Murphy and left "Deposits" by the J.W.... She was appalled and my Mother was embarassed.
