This is a hard one to ask but I need honest perspective.
14-yr-old mixed breed. CKD diagnosed last year, managed with diet + meds. Still has good moments — tail wags when I come home, eats most days, recognises me. But the bad days are getting more frequent. Last week she fell twice trying to navigate stairs she's used for 10 years. She seems confused at night.
I’m not asking anyone to make this decision for me. I’m asking how YOU knew. What signs were the final ones for you?
This is the hardest thing about being a dog owner. I'm sorry you're here.
For my Golden last year, I used a quality-of-life scale — the HHHHHMM scale (Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, More good days than bad). It’s not perfect but it took the decision out of my emotional brain and into something I could track.
What made it clear for us: the “more good days than bad” flipped. For months I’d been counting good days — she ate today, she wagged today, she sat with me today. Then one week I realised I’d been counting bad days instead — she didn't eat, she didn’t come to the door, she stayed in bed. The math changed and it became my answer.
The other thing that helped: I asked my vet directly, “If she were your dog, what would you do?” She didn’t tell me what to do but she told me what she would consider, and that gave me permission to think about it without guilt.
One thing I wish someone had told me — you will never feel ready. There is no clear “now is the moment.” The right time is usually a few days before you think it is, not a few days after. Vets see this every week and they’ll tell you privately that owners more often wait too long than go too early.
I won’t add much — the above reply captures it better than a clinical framework can. The HHHHHMM scale (Dr. Alice Villalobos’ quality-of-life tool) is the closest thing we have to a validated instrument, and I do recommend owners use it because it externalises the assessment.
One additional consideration that doesn’t get talked about enough: cognitive dysfunction syndrome (canine dementia) is genuinely common in dogs over 12 and the confusion at night you describe is a flag. It’s treatable to some degree (selegiline, melatonin, diet changes, environmental enrichment) and worth discussing with your vet if it's a major contributor to her bad days. Sometimes a 4-week trial of cognitive support meaningfully improves quality of life — sometimes it doesn't — but worth ruling out as a reversible factor before assuming she’s near the end.
And please don't carry this alone. There are excellent grief support communities (Lap of Love’s online resources, the Pet Loss Support Hotline at UC Davis) for owners working through end-of-life decisions. The decision is yours, but you don’t have to make it in isolation.
