ELI5:Why is it that medical doctors can deal with a single species(humans),veterinary doctors are(assumed?)able to deal with every other species?

Most veterinary doctors don't deal with all species, you most often go to a different doctor for your snake than your horse.

Also vets tend to not go nearly as in depth as human doctors. People will do a lot for their pets but there is a lot less options for animal medicine than human medicine. Like animal organ transplants are very very rare (sometimes kidneys, basically never hearts or lungs), cancer treatment is simplified, diabetes treatment is very loose compared to human treatment, etc. You just do a lot less for each animal than you do for each human. It's still a complicated science but it's a little less down in any direction so you can handle more directions at once.
