Yes, I’m having the same problem as @raum. I remember linking it in another Q here but I’ve drawn a blank as to who asked the Q. I don’t remember the article addressing the Q as to how dogs could transmit covid. It seems to me that they commented that there is a canine covid that doesn’t transmit to humans.
My other thought is that since humans transmit via coughing & sneezing that it’s possible that, if dogs do transmit it on to humans, it would also be via their saliva. So, I would think it would be more likely through a cough, sneeze, or possibly licking the human. Also, how old is your mother??? I just read this week that now that they have some actual detail on who gets it that they’ve discovered that the 60 & 70 y/o groups aren’t that prone to get it, but those over 80 with underlying conditions that are more susceptible than others. Don’t know that is true, but that was in a CDC report earlier this week.
Actually, I don’t think the dog to human transfer rate has been high enough to be overly stressed out. IF it was a masjor problem, I think that we would have better info from which to draw!!!
