I needed veterinary related hours, so I mailed my resume and cover letter to all the vet clinics within a certain radius.
Only one clinic sent me an e-mail, but it worked out great! I started out originally as a volunteer (and as I discovered, they have a couple off and on volunteers) and was there everyday from morning until close and took Friday off for my own personal benefit (I was 2,200 miles away from my home state which in itself is a long story, so I wanted to do some sightseeing, etc).
I was actually offered a position as a kennel person, but turned it down because I would be doing more kennel work instead of the sitting in/assisting on surgeries, going on lots of farm calls and seeing all the fun alpacas/llamas, etc. I have never regretted my decision in turning down the $$. While I did help clean kennels when we were short staffed, so did the veterinarians in a crunch! Being a volunteer gave me the flexibility to ask more questions, learn how to run all the blood work, and more or less do the tech work.
I am grateful to the veterinarians that gave me this opportunity and glad I was in a newer, more modern facility with both large and small animals, exotics, etc. You never knew what was going to happen next and I really did discover I like a variety of animals (who knew I'd like working with llamas??).
But anyway, don't limit yourself on what type of veterinarian you'd like to send your resume to and I would personally check in with your veterinarian or a family veterinarian to see what they suggest on who to shadow or send a resume to. By the end of the summer, my horse's specialist (dang lame horse!) loved me and offered me a spot in his clinic, but the hour long drive was a bit of a deterrent when gas was so expensive.
In the end, my daily duties at the clinic ended up drawing up vaccines, sometimes checking clients in, prepping surgery animals (shaving, scrubbing them down), monitoring anesthesia during surgery, doing almost all of the blood work on the in house machines, snap tests, staining slides, surgery cleanup, pulling trach tubes and that sort of thing, restraining animals, going on farm calls so restraining large hairy animals that like to jump on you (aka llamas/alpacas), restraining dogs/cats/parrots/ferrets/whatever I had to do, taking x-rays, filling prescriptions, etc...I never knew what I was going to learn to do the next day!
