Agreed. Cats, dogs, horses, cattle, pigs, sheep and goats are the big ones. Those are usually covered extensively, even moreso in your specific area if you are at a tracking school. We not only cover disease and conditions (innumerable) but things like species-specific physiology,husbandry/management, reproduction, microscopic and molecular medicine in some cases, etc.
Then comes pocket pets (rats, mice, ferrets, guinea pigs) and wildlife and aquatics, camelids, exotics like birds and reptiles, also covered but in not so much detail.
But I agree with NoImagination's quote. The list and variation is extreme. It can feel like going to medical school for ten different species.
