There is no good day to make this decision, and there is no algorithm that will make it for you. What there is — and what veterinary medicine has spent the last twenty years building — is a small set of structured quality-of-life tools that translate a hundred quiet observations into something you can actually look at on paper. The two best-known are the HHHHHMM scale (Dr. Alice Villalobos) and the more recent JOURNEYS framework. Used honestly, they don’t give you the answer; they give you permission to see what’s already true.
This guide walks through both scales, what good death actually means medically, how to weigh “more good days than bad,” and how to bring this conversation to your vet. It’s written for the owner who would rather face this clearly, on their own terms, than be ambushed by a 2 a.m. emergency.
What “quality of life” actually measures
Quality of life in veterinary medicine isn’t a single feeling — it’s a sum of small, observable things: whether your dog can comfortably eat, drink, walk, sleep, and engage with the household without sustained pain or distress. The point of a structured scale is to look at all those dimensions on the same page, on the same scoring day each week, instead of letting a single good afternoon (or one bad night) dominate the picture.
Two scales dominate the conversation. Both are validated and both are free to use at home. The HHHHHMM scale, developed by veterinary oncologist Dr. Alice Villalobos, scores seven domains and is widely cited in AVMA end-of-life resources. The JOURNEYS scale, from Lap of Love, scores eight domains and is somewhat easier to use for owners new to the framework. Vets often use both alongside each other.
What neither scale measures: your readiness, your finances, your other pets, your kids, the holidays. Those matter — they shape the timeline — but they sit alongside the scale, not inside it.
The HHHHHMM scale, in plain English
Each letter is a domain scored 0–10, where 10 is “as good as it gets” and 0 is “no quality at all.” A total above 35 generally suggests acceptable quality; consistently below 35, especially with a downward trend, is the conversation point with your vet.
Hurt, Hunger, Hydration
The first three domains are the most concrete. Hurt asks whether pain is controlled, including breathing — open-mouth breathing in a dog at rest is a serious red flag. Hunger asks whether your dog is eating enough to maintain weight, with or without coaxing or hand-feeding. Hydration asks whether they’re drinking enough; subcutaneous fluids at home, given by you with vet guidance, can buy days to weeks of comfort. The skin-tent test we describe in our at-home hydration check works the same way at end of life.
Hygiene, Happiness, Mobility
Hygiene tracks whether your dog can stay clean, not soil themselves, and avoid pressure sores. A large dog who can no longer reposition is at real risk of sores within 48 hours. Happiness asks whether they still respond to family, treats, the leash, the door — the small daily anchors. Mobility asks whether they can walk to water, to the door, to a sleeping spot, with or without assistance like a sling or harness.
More good days than bad
The final M — and the one most owners feel hits hardest — is the running ratio. A week with five quiet, comfortable days and two hard ones is a different week from one with two okay afternoons and five hard nights. The scale exists so the math is visible. Many oncology teams ask owners to keep a simple two-column journal — “good day / hard day” — for two weeks before the conversation. It is one of the most useful clinical tools in the field, and it costs nothing.
The JOURNEYS scale (the eight-domain alternative)

JOURNEYS rescues some nuance HHHHHMM packs into a single H. The eight domains: Jumping (mobility/joint), Ouch (pain), Unkempt (hygiene), Rest, Eat-and-drink, Not themselves (personality changes), Engagement, and Your gut. Each is scored 1–10, with the running total compared week over week.
The “Your gut” domain is unusual and worth defending. Owners notice things — the angle a dog holds their head, the tone of a sigh, the way they look up when you come home or stop looking up at all — that no checklist captures. A vet asking you “what’s your gut telling you?” is asking for clinical information, not just emotional support. Trust that.
You can find printable versions of both scales linked from the AAHA owner education library. Print one. Hang it on the fridge. Score weekly, on the same day, with the same person if you can. It works.
Pain isn’t always obvious — what to actually watch for
Dogs evolved to hide pain. The cues are often quiet, and they’re easier to miss in the dog you’ve lived with for a decade because you’re seeing the gradual version. The classic late-stage pain signs:
- Panting at rest, in cool conditions, with no exertion. Persistent open-mouth breathing in a dog who isn’t hot is a strong pain indicator.
- Tucked posture, rounded back, hunched stand. Especially when getting up or settling.
- Reluctance to lie down — or to get up. A dog who paces at 2 a.m., stands in odd corners, or shifts position constantly is rarely just restless.
- Lip licking, swallowing, drooling at rest. Often misread as nausea; it’s frequently pain.
- Subtle social withdrawal. Not greeting you at the door. Sleeping in a new spot away from the family.
- Loss of normal grooming. Especially in cats, but dogs do this too — coat looks dull, dirty, matted around the rear.
Modern veterinary palliative care can manage most cancer pain effectively with multimodal protocols — usually a combination of an NSAID (where renal/hepatic function allows), gabapentin, and either a tramadol-class drug or transdermal fentanyl in late-stage cases. If pain is breaking through your current protocol, that’s a same-week call to your vet, not a “wait until next checkup” question.

What “good death” actually means in the room
Veterinary euthanasia is a planned, two-step procedure. The first injection is typically a heavy sedative — propofol, telazol, or a similar agent — that brings your dog to deep sleep within a minute. They are not aware of the second injection, an overdose of pentobarbital that stops the heart, usually within 30–60 seconds. The whole process from sedation to passing is generally under five minutes. There is no gasping, no struggle, no awareness. Eyes typically remain open; muscles may twitch briefly after the heart stops, which is normal post-mortem activity, not distress.
You can be present or not. You can be at the clinic, or — increasingly — at home, with services like Lap of Love or local mobile vets. Home euthanasia costs more (typically $250–$600 in the US versus $80–$200 in-clinic) but for many families is meaningfully gentler: the dog is in their bed, on their blanket, with their people, not on a stainless steel table. Both options are equally sound medically. Both are AVMA-aligned.
Aftercare is your choice and shouldn’t be rushed: communal cremation (no ashes returned), private cremation (ashes returned, typically $150–$350), or burial where local law allows. Most clinics will hold your dog for 24–48 hours so you can decide.
Anticipatory grief is not weakness — it’s information
The grief that begins before your dog has died — the heaviness in the weeks of declining quality, the bracing every morning to check whether they ate, the bargaining — is anticipatory grief, and it has its own clinical literature. It is not pathological. It is, often, the moment you start to know.
Owners regularly describe a moment, sometimes days or sometimes weeks before euthanasia, when a kind of internal clarity arrives — usually the morning after a particularly bad night. That clarity is real data. It typically lines up with the quality-of-life scores having drifted down for a stretch, even if you hadn’t been writing them down. Trust it. Bring it to your vet. The conversation goes better with the vet’s expertise on top of your reading of your own dog than from either alone.
Pet-loss support exists — both the ASPCA pet-loss line and the Tufts University Pet Loss Hotline are free. Use them. Talk to your vet’s social worker if the practice has one. Talk to people who have done this before. The grief is real and the company helps.
Frequently asked questions
How do I know it’s “time”?
The most honest answer most vets give: when there are more bad days than good, when pain is no longer manageable on the current protocol, or when one of the cardinal functions — eating, drinking, breathing comfortably, eliminating without distress — has been compromised for more than a few days. Quality-of-life scores below 35 (HHHHHMM) sustained over a week is a common practical threshold.
Should I wait for a “natural” death?
Most veterinary palliative-care specialists would gently say no. Natural death from cancer in dogs is rarely peaceful — it typically involves bleeding, respiratory distress, or organ failure, often at night, often in the home with no clinical support. A planned euthanasia, on a day you’ve chosen, with the people who love them present, is generally far kinder. The exception is hospice support with strong pain control where the dog is still genuinely comfortable; many vets work in that mode for days to weeks.
Can I bring my other pets to say goodbye?
Yes, and many home-euthanasia vets actively recommend it. Pets in the household often understand that their housemate is gone in a way they don’t understand absence. A few quiet minutes after passing, with the surviving pets allowed to sniff and process, often reduces searching behavior and unsettled grief in the days afterward.
What about cost — what does this typically run?
In-clinic euthanasia in the US generally runs $80–$200, with private cremation adding $150–$350. Home euthanasia services typically charge $250–$600 including travel and aftercare coordination. Many clinics offer payment plans or work with CareCredit. If cost is the deciding factor between in-clinic and waiting, talk to your vet — most practices will work with you rather than have a dog suffer.
Is my dog suffering right now?
Honest answer: you can’t always tell, and that’s why the structured scales exist. If you can’t tell, score them today and score them again in three days. If both scores are below 35 and trending down, the conversation with your vet is the next step. If pain control is holding and the dog is still eating and engaging, you likely have time. The framework lets you stop holding the question alone.
How do I tell my kids?
Briefly, honestly, and at their level. “Buddy is very sick. The medicine isn’t making him better anymore. The vet is going to help him die without it hurting, so he doesn’t have to feel sick anymore.” Avoid euphemisms like “put to sleep,” which can confuse young children about bedtime. Many families find it helpful to involve children in choosing a special meal, a final walk, or a goodbye ritual. The ASPCA pet-loss page has age-by-age guidance.
