Three cases — what good and bad euthanasia decisions actually look like

Preface — what these are

Three composite cases. Drawn from a decade of practice; identifying details changed; clinical features and conversations preserved. Each is presented in the format I find most useful in teaching — diagnosis, decision sequence, what worked or did not, and the lesson that travels.

Case one — the timely week

Animal. Daksh, a 13-year-old male Labrador. Lymphoma, multicentric. Palliative prednisolone after the family declined CHOP chemotherapy on quality-of-life grounds.

Decision sequence. Diagnosis at week zero. The family started a weekly HHHHHMM tracker. By week six, total scores were trending from 52 down to 41 — gradual, mostly the Hunger and Happiness axes. At week eight, the dog had a strong day on a Sunday and a poor day on Monday. The family scheduled the home euthanasia for the following Sunday — eight days out.

The week between. Daksh was given everything he wanted. Two short walks per day at his pace. His favourite peanut butter every evening. The grandchildren came over on the Wednesday. The vet visited on the Saturday for a non-procedural check-in to allow the family to ask anything.

The day. Home, in the back garden, on his bed. Sedation took 12 minutes; lethal injection 90 seconds. The family stayed with the body for an hour. Cremation arrangements had been made the previous week.

What worked. The week of notice. The family knew what was coming, said the things they needed to say, and arrived at the day prepared rather than ambushed. The chart said it was time before the household had to argue about it.

Case two — the wrong vet

Animal. Mia, a 16-year-old female domestic shorthair cat. Stage 4 CKD. Clinically refractory.

Decision sequence. The family had been managing the cat at home for fourteen months with sub-Q fluids, mirtazapine, and a renal diet. Decline accelerated; appetite collapsed over five days. Family reached the welfare threshold and called a vet who advertised home euthanasia.

What went wrong. The visiting vet — not the family’s usual practice — arrived running late from the previous appointment. Asked perfunctory questions. Did not warn the family about reflex movements. Did not offer adequate pre-procedure time. Sedation appeared shallow when the IV was attempted; the cat reacted to the second injection. The family was distressed; the cat was likely distressed. The whole appointment ran 25 minutes.

What we learned. The drugs and the protocol are usually fine. The variable that decides whether a euthanasia is good or bad is the practitioner’s pacing, depth of sedation, and willingness to take the time. The eight questions exist for cases like this — not to make the vet feel doubted, but to filter out the practitioners who will rush. See the questions in our city guides.

Case three — the late conversation

Animal. Bruno, a 12-year-old male German Shepherd cross. Severe osteoarthritis with progressive paraparesis. Cognitively well.

Decision sequence. The family delayed the euthanasia conversation by approximately three months past the welfare threshold. Multiple readers of the dog’s state — vet, dog walker, brother of the primary owner — had raised it. The primary owner was unable to bear the decision.

What happened. Bruno developed pressure sores from prolonged recumbency. He could no longer rise without two-person assistance. He was incontinent in the house, which he had previously been ashamed of (for a sensitive dog like Bruno, this matters). The family tube-fed him for the last fortnight. Euthanasia eventually happened in the clinic in a partial crisis, with the family arriving late at night.

What we learned. The most common regret I hear is not "we did it too soon." It is "we waited a fortnight too long and the last fortnight was awful for both of us." The euthanasia conversation belongs at the welfare threshold, not at the crisis. The threshold is the welfare of the animal; the crisis is the family’s readiness — and waiting for the second imposes the cost on the dog.

Three lessons that travel

Schedule a week ahead when you can. The week is for the family. The dog is fine for the week, with appropriate care.
Choose the practitioner more carefully than the venue. A rushed home visit is worse than an unhurried clinic appointment. The eight questions filter for the right practitioner.
The threshold is the dog’s welfare, not the family’s readiness. Both matter; only one decides the date. The family’s readiness is what good consultation is for. See consult.

Common questions

Are these real cases?

They are composite cases drawn from a decade of practice — combinations of real animals and real owners, with identifying details changed. The clinical features, the conversations, and the outcomes are real. The names and exact circumstances are not.

Why three cases instead of one?

Because the spread of outcomes is the most useful teaching. A single case looks like a story; three cases reveal the variables that matter — timing, practitioner choice, and the conversations the family has or postpones.

Can I share my own case anonymously?

Yes — through /consult or by email. We anonymise identifying detail. Real cases shape what we teach; we are grateful for the trust.

Do you discuss cases with other vets in supervision?

Routinely. Difficult cases are reviewed in peer supervision; difficult conversations are reviewed in clinical-ethical supervision. Practising end-of-life veterinary care without supervision would be unsafe — for the practitioner and, downstream, for the animals.
