Sadly, vets have a high suicide rate. This study found 1.6x the general population rate for male vets and 2.4% for females.

I have a vet friend that I talk to a lot. One thing that struck me was how many clients will bring in a dog with a serious, obvious malady (the one I remember was a dog with maggots in its anus, sorry for the visual) and will be like, “are you sure he’s in pain? He hasn’t been crying all day”. And it will be evident that this has been happening for weeks.
