When on holiday a GP I know tells people they’re a vet.
Two things:
1) a friend of mine fell off his bicycle outside a vet’s practice. He was given excellent first aid.
2) Vets need to know at least something about almost everything medical concerning warm-blooded animals. They are generalists par excellence. To be honest, I would rather be treated for relatively minor injuries by a vet than by a brain surgeon or gynaecologist.
