Sounds like what my Ziggy had during the summer and his vet thought it was giardia. I remember him trying to poop on the front lawn and passing gas with lots of noise and looking over his shoulder with a "What the hell was that ???!!" expression. He was treated with antibiotics and has come through with no lasting problems. I would think a stool test would be one of the first things a vet would check because its cheap, easy to get and non-invasive.
