If dog hasn’t been exposed to the pathogen for a while ie parvo in environment or shed MLV virus in urine/poo from over vaccinated dogs the titer can be negative. Like us they don’t always keep antibodies circulating if not needed, if not fighting at the time. They have cellular immunity. To raise titer get dog exposed to the pathogen.
Ok now I understand, when not fighting anything the antibodies could be lower. I believe this was being discussed in Red Blood cell counts in humans also recently.
After a pup has seroconverted its immune for life. Titer can be negative but dog is immune antibodies are not immunity.
I assume their immune fighting ability might be enhanced then, though not giving them overall immunity prevention.
I don’t know what your saying but once a pup is immune through natural exposure or jab, that’s it they are immune.
I was referring to this, so was trying to understand and maybe stated wrong.
"but dog is immune antibodies are not immunity."
