For what it’s worth, my cousin once took his dog to the ER.
He’d been near the hospital with the dog, and something happened where the dog was hit by a car (I’m not sure of the exact circumstances.) My cousin is not the brightest bulb in the pack, and he paniced. Looking up, he saw the hospital ER sign. He picked up the dog and ran in there.
Lucky for him and the dog, the ER was having a slow day, and the doctors there fixed the dog right up.
I do small animal medicine and surgery; dogs, cats, reptiles, birds, guinea pigs, ferrets, etc. In my area I am the only veterinarian who sees birds and reptiles. Not far from me is a feline-only practice. About once a year I will do some equine work for a friend who cannot afford a “real” equine vet.
I have sutured a few lacerations for friends during camping trips/holiday parties/drunken orgies. For all I know this is a violation of the law, however. I have removed a few bothersome skin tags from my own body using local anesthesia.
I have never met a veterinarian who did not self medicate friom their pharmacy when the need arose. That said, a colleague of mine treated herself for some “minor” problem. She had an adverse reaction to the medication and ended up hospitalized.
I have always thought about doing “back alley” abortions should they become illegal. Not seriously thinking, but it could be a lucrative sideline.
And in doing so, violated many laws that regulate the practice of medicine, both human and veterinary. I have been advised that should a human have an injury while in my office, I should offer to call an ambulance. Period.
Well doctors are vets who have specialised in one single animal species 
Well- some things, like for example, suturing a minor wound, or administering an injection, I’d have no problem letting a vet do, because then all that matters is skin, fat and muscle, and the ability to wield a needle with some skill, and the techniques are beasically the same regardless of species.
For diagnosing the cause of a funny feeling in my abdomen, prescribing medications, or performing surgery I’d rather see a doctor.
Other than wrapping a sick animal in a blanket and taking it to the vet, and being able to recognise when an animal is in shock or pain, I haven’t got the foggiest notion of what to do with them- that’s why vets are there!
Just popping in to point out that the vet does not have access to the single most valuable diagnostic tool an MD has. The vet can’t ask the patient, “How do you feel?”
I think we’re getting off track from the original question. Anybody with medical training is better than Aunt Betty and her castor oil. For dog, human or newt. Would we really want to have a basic check-up from someone who specializes in newts? If you are a newt, yes. But if something suddenly goes wrong you will be damn glad for any help you can get.
I’m a newt.
You’ll get better.
But in a (diagnostic) laparatomy, the vet can simply cut the patient open from the xiphoid process to the pubic symphysis - a practice not recommended for people who might want to hit the beach any time afterwards.
One of my favorite Will Roger’s quotes
There was an article in the NY Times Science section a few months back that talked about leveraging dentists and their offices in the case of terrorist attack/natural disaster. The justification was that their offices are well equiped with sterile instruments and anasthesia. They can suture wounds and I’m sure other activities that I can’t name off the top of my head right now.
I heard an interview on NPR with a guy who had gone to school to be a vet, but never opened practice, preferring to be a mountain climber. When asked if his vet training had come in handy with dealing with injured pack animals and the like, he replied, “Actually, I’ve used it more on people than I have on the animals.”
Neither can I.
But so can I.
But people don’t expect your patients to get up and walk out.
