Yup, my pringle used to really let rip . sometimes he,d turn to check nothing else "passed" along the way. His other trick was slurping half a bowl of water on the floor then stretching up to me on the settee & burping in my face, still licking his lips then if I was "lucky" I,d get another snorter for good measure.
I cant remember if he got worse as he aged coz it was always bad.
I recon boxers should be getting blamed for global warming!!
