Question
I have an older relative staying with my immediate family. At first he and our dog got along fine. It was when my relative became very ill and subsequently required temporary hospitalization when my dog started growling at him. I don’t know if the dog is picking up on some instability or something like that.
I don’t know if it matters but the dog’s breed is mixed but mostly a Golden Labrador and has been a wonderful family pet. The relative has late stage liver cirrhosis and many of the complications that come along with that type of disease.
Answer
Dogs rely insanely strongly on their sense of smell, including to identify people. When someone gets ill, depending on their disease, their odor becomes distinctly different. You may have heard of dogs sniffing out cancer etc. Unfortunately it is not unheard of that dogs behave differently around people who fall sick. Sometimes they become apathetic, sometimes more calm, sometimes they get aggressive. The exact reason is hard to pin down, but aggression is usually fear-based or territorial, so it may be confused by your family member smelling different or protective of its owners.
