I was washing Buzz’s butt daily and additionally hosing the excrement off twice a day. It was black, terribly smelly and caked hard on his white hind legs and throughout his tail every morning, then throughout the day, non-stop. My barn was inundated with this foul smell. I was at my wit’s end and concerned about his health and weight loss. While he is still gassy, that is what is coming out – gas. He seems to be on the road to recovery.
