I know various fragments of information from helping around the place where I lease a horse, deworming them, giving them bute, grooming them. I know quite a bit about actual riding, but not much about the horse. I'd read a book, but I have ADHD and really have trouble reading past page one unless something beyond insanely interesting shows up. I want to learn more mostly because I want to be a equine veterinarian, and I'm going to be behind anyone else if I go to college and don't know 1/8th of the stuff everyone else knows. I'm going to ask my instructor if I can hang around some day he's doing vaccinations or something to see what happens and yeah.
Where's a good place to start learning for someone that basically knows nothing?
