I've definitely seen how vets have transitioned over the years, from being James Herriot to a business. I was another who wanted to be a vet as a child, but couldn't cope with the thought that they may not survive. I think most vets do care, but like surgeons have to maintain a distance so they are not emotionally involved, and that's something I couldn't do.
These days I am probably a vet's worst client as I question and research everything. I had one vet try to give 3 different pain medications after a minor surgery which would have knocked the poor dog out for weeks, and probably caused all sorts of other problems long term, and they weren't happy when I refused
I think we have to advocate for our pets, actually all animals, in the same way we have to advocate for ourselves these days.
