I should have euthanised sooner — the asymmetric regret

The short answer

If the regret you are carrying is "I waited too long," you are in the company of most pet owners who have done this work. The asymmetry — that "too late" is the dominant retrospective regret rather than "too soon" — is one of the most consistent observations in the pet-bereavement literature. It does not mean the decision was wrong. It means hindsight saw what foresight could not.

The asymmetry

Across surveyed pet owners, in-home euthanasia networks, and bereavement counselling case notes, the same pattern recurs:

"I should have done it sooner" — the most common timing-related regret.
"I should have waited longer" — also occurs, but less often, and usually fades within months.
"The timing was right" — the goal, achievable in most cases with structured assessment.

The asymmetry is structural. Owners who delay see, in retrospect, the welfare data that was already in front of them. Owners who act on time do not have a counterfactual to test. The two scenarios produce different regret signatures.

Why this regret is so common

Five reasons, mechanical rather than moral:

Welfare decline is gradual. A pet who has been steadily losing one HHHHHMM point per week looks similar to yesterday on most days. Owners adapt to the new normal without registering the cumulative loss.
Good days mislead. A dog who has a strong morning, who eats with apparent enthusiasm, who looks at you and wags briefly — that moment lives in memory. The sustained welfare data does not, until you look back at the tracker.
The act of deciding is harder than the act of waiting. Postponing a decision feels like compassion in the moment; it can produce its own welfare cost.
Vets are sometimes too cautious. Clinical training emphasises preserving life; the welfare-led conversation about ending it is often initiated late.
Households disagree. A partner, a child, a parent who is not ready can extend the timeline beyond what the welfare data warrants.

How to make peace with it

Three things, in order of impact:

Distinguish hindsight from foresight. You did not have, in real time, the welfare data you have now. The decision you would have made if you had known is not the decision you actually had to make.
Accept that the regret is information, not verdict. The feeling tells you something about your care, your attention, your future decisions. It does not tell you that you failed.
Tell someone the full story. Once or twice. The act of putting it in words organises the experience and reduces the recurring loop.

How to do better next time

For the next pet, four practices that tend to help:

Score the HHHHHMM rubric weekly when chronic illness arrives. Not when it gets bad — when it arrives.
Set a threshold in advance with your vet. "If we drop below 35 sustained for two weeks, we have the conversation." Written down.
Identify a default off-ramp (sedation + euthanasia at home; or scheduled clinic visit) and a default vet to do it.
Tell the household, in advance, who decides. Diffused responsibility extends timelines.

Common questions

Did I really make my pet suffer by waiting?

Maybe, partially. Welfare in late-stage decline often is not what owners think it is when the trajectory is downward. Looking back, the pain or fatigue or hiding may have been more meaningful than it seemed at the time. The fact that you are asking the question is itself evidence of your care.

How can I forgive myself?

Slowly. The feeling is real. The decision was real. Both can be true. Forgiveness here is not about deciding the choice was right; it is about recognising that you made the best decision you could with the information you had at the time, and that hindsight has more information than foresight.

Should I tell anyone about this regret?

Yes, ideally. Spoken aloud once or twice, this regret loses some of its weight. Carry it silently and it can amplify. A trusted friend, a counsellor, or a pet bereavement helpline can hear it without judgement.

Will this make me act too soon next time?

Often, yes — and that is sometimes appropriate. Many owners who lost a previous pet too late report acting earlier with the next one, with no regret about the timing. The lesson is real and worth carrying, as long as it does not become its own anxiety.
