Accidents happen and animals are unpredictable, especially under stress. I've had normally nice docile pets "turn" on me because they are stressed out, scared, hurt, etc. A good friend of mine that happens to also be a veterinarian and was a classmate of mine in vet school got part of his nose and lip torn off by a Chow Chow he was examining. Chows are known to be aggressive but this one had never acted aggressive before so it's file was not "flagged". The dog just decided it didn't like what my friend was doing and gave no warning whatsoever. He had to go through some intensive reconstructive plastic surgery and decided after that to leave private practice and now works for a well-known pet food company instead.
Yes, people do dumb things, but I don't think anyone "asks" for it or expects it to happen. This is why I often do not allow owners to restrain their own pets in the exam room or for procedures. Sometimes they take offense to this and get really insistent that "he trusts me and would never do anything." And sometimes that is true, but I don't want anyone to find out the hard way that they were wrong. Not only do I not want anyone hurt, it's also a liability issue for the practice - we can be sued by an owner who gets injured by their own pet while being treated at the hospital. There's also a big difference between someone who just gets nipped at or barely hurt by a dog bite and learns their lesson, and someone who gets half their face ripped off. One can express their sympathy and support if they feel it is appropriate, rather than just making things worse with "Hey, serves you right!" Sure it is the anchor's fault, and not the dog's fault, and I hate to see another breed get saddled with bad rap (just like Pits, Rotties, etc.), but severe dog bite injuries are not something I would wish on anyone (except Michael Vick).
What I really hate is when people get right into their scared CAT'S face. Kitty is on the table, growling and hissing, I have a tech safely holding Kitty for me to give vaccines to, and owner insists on getting their face an inch from Kitty's face, petting it and cooing at it. And I have to be the bad guy that says, "I wouldn't do that if I were you..." Because while my tech might have a good grip on Kitty, it doesn't take much for Kitty to spaz out and get out of that grip...and then your face and eyes are going to get scratched and bit to pieces. As bad as dog bites can be, cats can also really mess you up.
Remember too, how biased local news reporting really is...they are after ratings and a "big story", not always about presenting a story that is fair and balanced.
