Wow, people have already mentioned a lot of the great things that keep me coming back... especially after days like today, when the hospital is almost busting at the seams, we're shortstaffed, and everybody is running around like crazy chickens.
I work in the ER/CC dept of a specialty referral hospital, so unfortunately I don't get to see a lot of the long-term client/patient stuff as I would like. People only bring their animals to us when things are already going pretty crappy, and they often get worse from there. One of the things that draws me to this field is the opportunity to work with people and their pets long-term, ideally from when they first come in with a new pup, to be able to "mold" them into the "ideal" petowners so they can all have a long happy healthy life together. Hopefully, as a DVM, I will have that chance.
But one thing that jumps out at me recently is my personal experience when my 10 yr old labmutt suddenly developed a slight head tilt, ataxia, anorexia, vomiting. Other than the head tilt, none of those things are totally unusal for her - she's old, getting a little wobbly, has always been a finicky eater, and often eats disgusting stuff she finds and pukes it up later. But all together, with the tilt, was worrisome. Of course, with the "worst cases" I typically see at work, my mind races to "Brain tumor! Cancer! Stroke! " But the other part of me also doesn't want to over-react - could be any number of less serious causes. But when it hadn't resolved after two days, I finally said I've gotta bring her in.
I brought her straight into my ER on a Sunday afternoon, and it happened to be - amazingly - a slow moment. And it was one of those times you just feel so lucky to be in this field. I sat right down in the office with three very experienced doctors who I have great respect for. They watched her walk around for about 10 seconds while listening to me, and almost simultaneously said "Oh yeah, she's got Old Dog Vestibular Disease." They all did a little exam, debating the causes of ODVD, explaining it to me and answering my questions and reassuring me. And I thought, wow, how awesome to have access to this great knowledge and resources, and to be a part of this vet med community. So, maybe that's a little selfish, but ultimately all of what I'm doing helps me be a better caretaker for my own pets.
