> It has been noted that guide dogs working in towns breathe the same pollutants as humans yet do not have asthma. Could this be because when they lie on their chests the kickback from the upper ribs keeps the corresponding vertebrae mobile, allowing the sympathetic system to work efficiently?
Or could it be one of the many other physiological differences between humans and dogs ?
I think the author notes that this is mostly a collection of anecdotal observations, but linking a primarily inflammatory disorder like asthma with musculoskeletal problems is a bit far fetched in my layman’s opinion. Sounds a bit like chiropractic quackery to me.
