Everyone i have talked to has told me that buying any kind of book is a waste of money since i am going to go through plenty while working first towards a bachelors in animal science and then apply to vet schools.. but i wanted to find something (possibly a CD-ROM or DVD) "walk through" of some sort that could help me get a better overall feel of the field and point out the most common and basic things seen and used in an everyday small animal veterinary clinic in the US.
