While difficult cases are not the ones that anyone wants to remember, with time and experience, you will have at least a few that you can refer to. The interviewer is not trying to get you to relive a traumatic experience but wants to see the humane side of you and to see that you are able to feel compassion, despite having to work a difficult situation.
"One of my most difficult cases was actually a case when a young boy came in with his horse that had to be euthanized. His dad told him he didn't have to be present, but he said 'He carried me a lot and I want to stay with him until the end.' When I think of that case, I am reminded to be compassionate and to always remember that every animal I care for is possibly loved by some little boy or girl."
"I am a new veterinarian and really don't have a really difficult story to share since beginning my career. I do remember the first time I tended to an animal that was going to die, though. When I was a young teen, a mare tried to deliver a colt on our farm. The colt was breached and by the time we got to her, the mare and colt were both in extreme distress. My dad called the veterinarian to assist, but there was nothing they could do."
"The most difficult case I have worked, was when I was assisting with some rescue dogs that were used as bait dogs for a dogfighting ring. A few of the dogs that were brought in had to be euthanized right away. It was one of the worst cases of animal abuse I have ever witnessed."
