@ crisw What I mean is that often (if not most) times people simply clump all the things that give the symptoms of a cold together in one category that they label as a cold (and i’m not talking about the same symptoms but to an extreme level, such as bacterial bronchitis would produce, I’m referring to the same symptoms and at the same levels). When in fact they’re not always inflicted with an ACTUAL cold.
Some of those species are most definitely transmittable between species. (I can vouch for this personally as I’ve gotten sick with cold-like-symptoms, at the same time as my dog multiple times in the years I’ve owned him)
