"In reality, I won't run into this situation ever because I'm going into behavior not medicine."
What are you going to do with the owners who want to euthanize their pets because of behavior problems? You WILL run into these situations. They come up day in and day out. Obviously as was stated before, there is no right and wrong answer to these dilemmas. Saying that in the case of a HBC you would waive fees or adopt the dog is maybe feasible a few times, but if you are an associate veterinarian in a clinic you can believe me that this will not fly with your boss all too often. HBC cases can be thousands of thousands of dollars to "repair" and not always with the best prognosis or best outcome for the patient. There is no way that an associate can adopt every stray or every pet from an owner who can't afford payment. As we all know, or at least those of us who have actually worked in private practice know, payment plans do not work. Clients would do better to obtain Care Credit or another credit card. And those of us who have worked out there know all too often a person will come in and say "do everything to save my dog" and you do and run up a huge bill that is never paid and the animal is never picked up.
Regarding euthanizing the wrong animal, it is foolish to think that this does not go on in the real world. In fact, I was just discussing this with a resident at my vet school yesterday and she told me it happened during her internship last year at a very elite private practice referral place in Florida. There is no excuse for it, but it does happen. I don't think it's common for a situation where a perfectly healthy pet is euthanized in place of a sick one. The one being euthanized by mistake is probably very ill as well. And sure things should be double, triple, or more checked. But the reality is that it happens. If this were an interview question you would not be wise to answer "that would never happen to me' because it very well could
Regarding breeders, this scenario will happen as well. Yes you could try and adopt out the puppies or buy them from the breeder or whatever, but are you as the veterinarian going to offer free spays and neuters for those pups as well? Are you going to eat the cost of that plus buying the dogs? Because I think it's unethical to send those puppies out intact and able to breed on their own.
I don't know if people on this board have practical experience working in the veterinary field, but if you don't I would suggest getting out there and really making sure that you are able to handle the ethical and moral dilemmas that come up each and every day. Sure it's noble to say you are not in this for the money. And that's the right attitude to have. And no, I don't want to be cynical and say that everything has to be euthanized or that the picture is very grim. But to think that as an associate, or even a practice owner that you will be able to save every living thing that comes through the door (including those that are savable with no money) is completely unrealistic. You may spend thousands of your clinics dollars to save one dog, when you could have donated that money or time to a shelter and helped dozens of other animals. Things are not black and white and if you continue to have that attitude while in vet school, you will not only be disappointed and angry, but you will become bitter and jaded very quickly.
