Do dog's farts smell worse than cat's farts?

Based on what I have experienced of cat's farts, all I can say is that
I hope not. Scientific studies of farts show that cat's farts have a
higher concentration of odor-causing gases than dog's farts, but dog's
farts have a larger volume. The two factors equalize out (the same
number of stench molecules for both), so the odor is about the same.
