Yeah, the people I know who work in veterinary healthcare love animals. Many of them end up burning out because they have to deal with so much animal death.
A handful of years ago, we had to euthanize our (very old) cat. The plan was to have an at-home come in, but his conditioned worsened, and the service couldn't accommodate us, so I ended up going to an emergency clinic. Initially, it was a bit impersonal, but I was touched by the vet who, when administering the drugs, started crying right along with me.
