Maybe we should be glad it was Spork and not a bigger dog, because it sounds like this idiot of a vet tech would be one of those screaming for a breed ban from the rooftops.
Seriously dude...you work with animals in a stressful situation, there is a risk that you will get bitten at some point. I worked in a busy boarding resort. I was very good at handling the stressed out animals without getting bitten, but even still, I knew there was a chance. I was bitten a couple of times by some smaller dogs, but never to an extent of needing more than a cleaning and bandage with some neosporin, mostly because I was aware of what was going on and usually got mostly out of range when they struck.
