Assessing Rectal Gases in Dogs

It has long been known that a little hydrogen sulfide (HS) contributes a lot to the distinctive odor of intestinal gas. Researchers at the Waltham Centre for Pet Nutrition in Leicestershire, U.K., report a series of experiments that confirms this wisdom and validates a treatment approach for reducing the malodorous fumes from one's canine.1 The successful recipe combines activated charcoal, which sequesters HS in its nooks and crannies; zinc acetate, which binds the gas; and an extract of the yu
