I've worked for a vet for over 2 years now and I love it!! You will learn a lot working behind the scenes. Hopefully you won't get stuck up in reception all day-that's the most boring part in my opinion. I love working in the pharmacy and helping out the doctor in the exam rooms. I also love assisting in surgery, doing x-rays, and taking care of the animals in the ward.
Unfortunately this field is a very low paying field to work in. It really amazes me how a cashier at home depot could make more than a vet tech who is saving animal's lives. But if you really love your job, it's so worth it, so good luck!!
