Interesting, (and factual) article. Working in veterinary hospitals a long time ago, for me, I've gone thru ring worm, complete disinfecting processes when I've been sprayed with blood, handled leukemia cats, parasites, giardia dogs often having to change my clothes and scrub before going home to my own pets and kids. Now, as a kennel owner, I'm all too aware of how crutial it is to keep a very sanitary environment when dealing with multiple dogs. Some of the viruses and parasites these days are pretty horrendous. Does this change how I handle my own dogs? Nope... I must admit I share food, they sleep with me on occassion, and we love a good snuggle. I just make sure they are in good health, very regularly wormed because of the other animals and livestock they're exposed to and are kept very clean.
