Dog Quality of Life Scale (HHHHHMM): Printable Scoring Guide

What the HHHHHMM Scale Is, and Why It Exists

Dr. Alice Villalobos, a veterinary oncologist, first described the scale in 2004 to help families and vet teams judge whether home care for a seriously ill pet was still working (Villalobos, 2011). She calls her approach Pawspice: pain and symptom relief alongside gentler treatment, starting when a life-limiting disease is diagnosed and becoming hospice as the pet declines.

The scale also shows where care can improve. A low Hygiene score may call for better bedding, not a goodbye.

In a 2026 online survey of 228 owners in 17 countries, only 7.3% had used a structured quality-of-life tool when facing euthanasia (Kiss et al., 2026).

How to Score It Fairly

Quality of life is a subjective judgment, shaped by your bond with your dog (AAHA 2023), and love and grief can tilt the numbers. Habits from Ohio State's Honoring the Bond program help:

• Set a fixed schedule, such as every three days or every Tuesday. The scale is most useful for tracking change over time (Ohio State).
• Score separately, then compare. Each family member sees the dog differently, and each person's anticipatory grief colors the view (Ohio State).
• Ask an outsider. Someone who sees your dog less often may notice a slow decline you have adjusted to (Ohio State).
• Look back at photos or videos from before the illness (Ohio State). AAHA suggests taking new ones at set intervals.
• Let Hurt override the total. Unrelenting pain or extreme difficulty breathing means very poor quality of life, whatever else is going well (Ohio State).

Judge your dog against their own normal. Lying around all day may be fine for one dog and a sign of trouble in another (Ohio State). Don't wait for the next scoring day if your dog is struggling to breathe or seems to be in severe pain; contact your vet or an emergency clinic now (Merck, Villalobos).

The Good-Day/Bad-Day Calendar

A calendar or journal of good and bad days gives a more objective view of change (AAHA 2023), and a happy or sad face per day is enough (Ohio State). First, list three to five things your dog loves, such as the evening walk or greeting you at the door. When your dog is consistently unable to enjoy them, Ohio State suggests it may be time to talk about euthanasia.

VCA counts nausea, vomiting, diarrhea, seizures, unrelenting pain and trouble breathing among the things that make a day bad.

Other Tools, and What the Research Says

Very few validated quality-of-life scales exist for pets, and most found online are not validated (AAHA 2023). A 2015 review of 52 quality-of-life instruments for dogs found only 11 with evidence of reliability or validity (Belshaw et al., 2015).

The HHHHHMM scale is no exception. Villalobos wrote in 2011 that there were no clinical studies of end-of-life quality-of-life assessment in pets, and an Italian validation study with 314 participants found only partial statistical fit (Testoni et al., 2023). The 35-point line is expert opinion. Other tools:

• Ohio State's worksheet turns HHHHHMM and other tools into a 1-to-5 checklist that includes hiding, panting at rest and weight loss. It is free in the How Will I Know? booklet.
• CORQ, from NC State, asks 17 questions on vitality, companionship, pain and mobility. In a small study, scores below 5.35 out of 7 were linked to a higher risk of death (Mondino et al., 2024). That flags risk; it is not a decision point.
• Chronic pain questionnaires such as the Canine Brief Pain Inventory (CBPI) and Liverpool Osteoarthritis in Dogs (LOAD) are the most widely used owner questionnaires, mainly for arthritis, and are free to use (AAHA 2022).

Signs of Pain Dogs Hide

Pain is easy to miss, so Hurt is easy to score too generously. Dogs change their demeanor, posture and movement to ease pain, so a quiet dog, or one off its food, may be hurting (AAHA 2022). Dogs in pain may not whimper, and some keep eating (ASPCA). Owners may explain the signs away and delay acting for months (AAHA 2022). Cornell's Riney Canine Health Center lists changes to watch for:

• Posture and movement: arched back, head carried low, stiffness, limping, trouble rising or climbing stairs
• Activity: pacing, trouble settling, lethargy, reluctance to walk
• Behavior: hiding, new clinginess, irritability, reacting badly to touch, licking or chewing one spot
• Face and breathing: flattened ears, a grimace, glazed eyes, panting at rest
• Daily habits: eating less, restless sleep, accidents in the house

Subtler reactions count too: holding the breath, lip licking or looking away when touched (AAHA 2022). Fear at the clinic can mask pain, so bring photos, videos or notes from home (Cornell). Villalobos writes that even partial pain relief can bring a remarkable lift in a pet's well-being.

Questions to Bring to Your Vet

Your vet can't decide for you but can give an honest medical view (Ohio State). Bring your scores, calendar and a short video. The first three questions come from Ohio State:

1. What are the best and worst case scenarios for each option?
2. How much pain do you think my dog is in?
3. Can you estimate how much time we have?
4. How is this disease likely to progress, and which signs mean death is near? (AAHA 2023)
5. What can we still improve? Some problems owners assume can't be managed do have options (VCA).
6. What do I do in a crisis at night or on a weekend? (Villalobos, AAHA 2023)

Tell your vet how you are coping, too. Owners who felt emotionally supported by their vet reported a lighter emotional burden (Kiss et al., 2026).

Palliative and Hospice Care

Palliative care relieves suffering and can run alongside treatment (AAHA 2016, AAHA 2023). Hospice, its final stage, runs from a terminal diagnosis until death, by euthanasia or by a natural death with comfort care, and supports the family too (AAHA 2016, AAHA 2023). Hospice is a philosophy, not a place; at home, you become your dog's main nurse (ASPCA).

Services can include an on-call vet, longer counseling visits, in-home care, comfort medications, in-home euthanasia and grief support. If your vet doesn't offer them, ask for a referral (AVMA). AAHA suggests a dedicated end-of-life appointment about a week after the need for hospice care is recognized, and a plan that covers:

• Who does what, with hands-on training for you (AAHA 2016)
• Home changes, incontinence care and safe handling to avoid bites (AAHA 2016)
• A daily plan and a crisis plan (AAHA 2023)
• Regular reviews, including video of your dog at home, and when to consider euthanasia (AAHA 2016)

Eating and drinking less is a normal part of dying, so expect Hunger and Hydration scores to fall near the end (AAHA 2016). AAHA's guidelines accept a natural death only with vet-supervised comfort care in place, and Villalobos advises a backup plan and knowing where to go at any hour. It is also fair to weigh your own limits of money, time, strength and emotion (AAHA 2023).

When the Scores Keep Falling

Villalobos treats a total below 35, or more than 3–5 bad days in a row, as a sign that quality of life is too compromised to continue hospice care. The AVMA asks a simpler question: are there more bad days than good? In the Dog Aging Project, owners most often gave pain or suffering (48.5% of euthanasias) or poor quality of life (24.8%) as the reason (McNulty et al., 2026).

There is rarely one clear moment, and no single right answer. Second-guessing is normal and doesn't mean you chose wrong; Ohio State's team says there is no wrong decision, only the one you feel is best for your dog and family.

Frequently Asked Questions

What score on the dog quality of life scale means it's time?

No score decides for you. Villalobos reads a total above 35 of 70 as acceptable for continuing hospice care. Uncontrolled pain or labored breathing means poor quality of life whatever the total (Ohio State). Use the score to start a conversation with your vet.

How often should I fill out a quality of life scale?

Pick a fixed interval, such as every three days or every Tuesday (Ohio State), and mark each day good or bad on a calendar in between (AAHA 2023). The trend matters more than any one score.

Is the HHHHHMM scale scientifically validated?

Not fully. Villalobos wrote in 2011 that there were no clinical studies of end-of-life quality-of-life assessment in pets, and an Italian validation study found only partial statistical fit (Testoni et al., 2023). Treat it as a structured guide.

Can my dog have a good quality of life if they can't walk well?

Sometimes, yes. Villalobos says a dog with limited mobility who is still alert and responsive can have a good quality of life if the family is committed to helping. Slings, carts, nonskid floors and careful hygiene help (AAHA 2016, VCA).

What if my family scores our dog differently?

That is normal. Each person interacts with the dog differently, and grief colors each view (Ohio State). Score separately, then compare and talk it through, ideally with your vet.

Should I use an online quality of life calculator?

A calculator only totals the scores you could add on paper. Most online scales are not validated (AAHA 2023), and none can examine your dog. Take your scores and notes to your vet.
