There is no objective threshold, and the decision is genuinely difficult — but there are structured ways to assess it that are considerably more reliable than trying to judge it moment to moment while distressed.

What euthanasia involves. An overdose of anaesthetic, usually given intravenously, causing unconsciousness within seconds and death shortly after. It is painless. A sedative is frequently given first, and it can be done at home by many practices, which is worth asking about.

The frameworks vets use, which are genuinely helpful:

Quality of life scales, scoring factors such as pain, appetite, hydration, hygiene, mobility, and — importantly — whether good days outnumber bad days. Scoring over time is far more informative than assessing on one day, because decline is gradual and you adapt to it without noticing.

The "five things" approach. List five things your animal genuinely enjoys — greeting you, a particular walk, a favourite place, eating with enthusiasm, playing. When they can no longer do most of them, that is the signal. Deciding the list in advance, while they are well, removes the temptation to move the threshold later.

A diary. Mark each day good or bad. The pattern becomes visible in a way that daily impressions do not.

What clouds judgement, stated honestly:

Adaptation. Decline is gradual and you recalibrate continuously, so you compare today with yesterday rather than with six months ago. Photographs and video from earlier are startling for exactly this reason.

Fear of acting too early — which weighs heavily and results in waiting until there is a crisis, frequently at night, in distress, with an emergency vet who does not know the animal. Slightly early is generally kinder than slightly late, and most owners who wait say afterwards that they wish they had not.

Guilt about cost, which is a legitimate factor and not a shameful one.

Anticipatory grief making the decision feel like a betrayal rather than an act of care.

Ask your vet directly. "What would you do?" is a fair question, and most will answer honestly if asked plainly.

Afterwards: cremation options, individual or communal, and support lines exist specifically for pet bereavement.
