Undertaking work experience is an essential part of every veterinary application. It will not only help you finalise your decision on whether veterinary is the right career for you, but is it is also used by universities to select applicants for interview.
Work experience gives you a chance to understand the role of the vet and experience different veterinary careers (e.g. farm vs small animal work as well as labs, their role in abbatoirs etc). You will be required to complete EMS (work experience but in your vet school holidays) so it gives you a chance to understand what will be involved in a veterinary degree, and also to work with different animal species so you can practise handling them and ensure that pursuing a degree with animals is what you want to do.
Different veterinary schools require different amounts of work experience prior to applying, and these can be found on each university website. There will be a summary page soon so stay tuned!...
For now, take a look at these tabs - there is loads of useful information about what to expect on work experience and how to make the most of them, including lots of photos provided by current vet students!
