So how do you see DNA with a $1000 visible light microscope? We're talking about DRIED samples as well. That nice fluffy erythrocyte looks a little different when you swab it off of the concrete.
I've seen things as small as DNA but it was with a $10,000,000 Zeiss (which I broke, but that's another story--OK it just happened to break while I was using it. You'd be amazed at what kind of repair service you get for a $10,000,000 appliance. The repair dude flies in from Texas ASAP. Very nice.).
You know what--if we are concerned about a human vs. an animal, ASSume it was a human trying to break in. Your great dane did well.
