And then some people will bring their healthy pets into the clinic for euthanasia because they're going out of town for a while and don't want to arrange for care of the animal in the meantime. Or because keeping the animal even if they are not leaving town has become too inconvenient. Some people are pieces of work.

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.
