I have an interest in being a vet, but will the require me to dissect animals?

Technology can be used to simulate operations and is a very useful tool but you still need to work on real animals. I am sure that you would rather practice on a dead animal rather than risk causing more suffering to a living one. I think the best thing would be to talk to people at a Veterinary Practice near you and tell them your interest and concerns and find out what it is really like. Maybe you could shadow a Veterinarian for a few days to see how you would get on.
