Can Dogs Get Sick From Humans
Can Dogs Get Sick From Humans
Good question! Many illnesses are caused by microorganims which include bacteria and viruses. In many cases these pathogens (organisms that cause disease) produce factors that help them colonize and infect a host animal - you, me, a cow or a dog. Superficially we look different from dogs. When you observe things more closely, you'll find that we differ in many other ways that are too small to be seen by the naked eye. The surfaces of our cell membranes, though similar in many respects, have many differences. Nearly all pathogens need to bind to cell membranes at some point so they can establish a "residence", or worse, get inside the cell to do some damage - bad for us, but good for the pathogen as the inside of a cell has a lot of food and nutrients.
So - the "hook" a pathogen uses to bind to a dog cell's membrane may not work on a human cell, and vice versa.
