Quick Answer
The Dog Quality of Life Calculator uses Dr. Alice Villalobos's HHHHHMM scale, scoring seven criteria — Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad — each from 0 to 10 for a total out of 70. A score of 56 or higher is Good, 35 to 55 is Acceptable, and below 35 suggests declining quality of life; Villalobos's guideline is that above 35/70 represents an acceptable quality of life. It is an educational aid for conversations with a veterinarian, not a diagnosis.
The dog quality of life scale scores seven areas — hurt, hunger, hydration, hygiene, happiness, mobility, and more good days than bad — each from zero to ten, for a total out of seventy; a score above thirty-five is considered an acceptable quality of life.
Key Takeaways
- The HHHHHMM scale scores 7 areas (Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, More good days) from 0-10
- Total out of 70: 56+ is Good, 35-55 Acceptable, below 35 Poor/declining
- Dr. Villalobos's guideline: a total above 35/70 is an acceptable quality of life
- Assess regularly and watch the trend — patterns matter more than a single score
- This is a guide for talking with your vet, not a diagnosis or a decision

Formula
Total Score = Hurt + Hunger + Hydration + Hygiene + Happiness + Mobility + More good days (each 0–10, max 70)
Where:
- QoL=Total Quality of Life score (0–70)(/70)
- S_i=Score for each HHHHHMM criterion(0–10)
Worked Examples
Comfortable Senior Dog
A 12-year-old dog with managed arthritis, eating and engaging well.
- 1Score each criterion 0–10
- 2Total = 8 + 9 + 9 + 8 + 8 + 6 + 9 = 57
- 357 ≥ 56 → Good quality of life
- 4Continue care; support mobility (ramps, traction rugs, joint care) and re-assess regularly
Dog with Chronic Illness (borderline)
A dog with kidney disease, eating less and slowing down but still enjoying some days.
- 1Total = 7 + 5 + 5 + 7 + 6 + 6 + 6 = 42
- 235 ≤ 42 < 56 → Acceptable but borderline
- 3Work with your vet on appetite, hydration (subcutaneous fluids) and pain control
- 4Re-assess every few days and keep a good-days diary
Dog in Decline
A dog with advanced disease, in pain, barely eating, and rarely engaging.
- 1Total = 3 + 3 + 4 + 4 + 3 + 2 + 3 = 22
- 222 < 35 → Poor / declining quality of life
- 3Speak with your veterinarian soon about hospice care and humane options
- 4This score is a guide for that conversation, not a verdict
Introduction
The Dog Quality of Life Calculator helps you objectively assess how your dog is doing, using the veterinarian-developed HHHHHMM scale by Dr. Alice Villalobos. You score seven areas — Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad — each from 0 (worst) to 10 (best). The seven scores add up to a total out of 70: a score of 56+ is Good, 35–55 is Acceptable, and below 35 suggests declining quality of life. This is one of the hardest parts of loving a dog, and scoring can bring clarity during a difficult time. This tool is an educational aid for conversations with your veterinarian — not a diagnosis or a decision. For related tools see the cat quality of life calculator and the dog life expectancy calculator.
How to Use the Dog Quality of Life Calculator
Score each of the seven criteria honestly based on the past few days, not a single good or bad moment. Use the help text under each field as a guide.
Rate each criterion from 0 (worst) to 10 (best) — be honest, not hopeful.
Base each score on a pattern over recent days rather than one isolated event.
Add the seven scores; the calculator gives a total out of 70 and an assessment.
Note which criteria score lowest — those are the areas to address with your vet.
Re-assess regularly (every few days to weekly) and watch the trend over time.
This calculator is a structured guide, not a diagnosis or a decision. Any score — especially a low one — should be discussed with your veterinarian, who knows your dog's full medical picture.
The Seven HHHHHMM Criteria
Each letter stands for one dimension of well-being. Understanding what each measures helps you score accurately.
| Criterion | What It Measures | Low Score (0-3) |
|---|---|---|
| Hurt | Pain control and ability to breathe comfortably | Uncontrolled pain or labored breathing |
| Hunger | Whether the dog eats enough to maintain itself | Refuses food or needs force-feeding |
| Hydration | Adequate fluid intake | Dehydrated; needs subcutaneous fluids |
| Hygiene | Staying clean, especially after toileting | Soiled coat, pressure sores, matting |
| Happiness | Interest, responsiveness, and joy | Withdrawn, unresponsive, depressed |
| Mobility | Ability to move, rise, and get around | Cannot move or stand without help |
| More good days | Balance of good days vs bad days | Mostly bad days over the past week |
Interpreting Your Score
The total out of 70 falls into three bands. Remember that the trend over time matters as much as a single number.
| Total Score | Assessment | What It Suggests |
|---|---|---|
| 56 – 70 | Good | Comfortable and enjoying life; continue care and re-assess regularly |
| 35 – 55 | Acceptable | Borderline; address the lowest-scoring areas with your vet |
| Below 35 | Poor / Declining | Talk with your vet soon about comfort care and humane options |
Dr. Villalobos's original guideline: a total above 35/70 represents an acceptable quality of life that may justify continued hospice care.
Signs of Declining Quality of Life
Beyond the numbers, watch for these patterns that often signal a dog's quality of life is slipping.
No longer greeting you, playing, or showing interest in favorite things
Persistent pain that medication no longer controls
Refusing food and water, or losing weight despite eating
Difficulty standing, frequent falls, or inability to get to the toilet area
Soiling itself and unable to stay clean
More bad days than good over a sustained period
Hiding, restlessness, or a vacant, disconnected demeanor
Supporting Your Dog's Quality of Life
A borderline score is often a call to action, not a conclusion. Many areas can be improved with veterinary support and home adjustments.
- Pain:
ask your vet about multimodal pain control — medications, acupuncture, laser therapy
- Mobility:
add ramps, traction rugs, orthopedic beds, and a supportive harness or sling
- Appetite:
try warming food, hand-feeding, or vet-prescribed appetite stimulants
- Hydration:
offer water frequently; your vet can teach subcutaneous fluid therapy
- Hygiene:
keep the coat clean and dry, manage incontinence, and prevent pressure sores
- Happiness:
keep gentle routines, favorite people, soft bedding, and calm company
Hospice and palliative ('pawspice') care focuses on comfort and dignity. A veterinary hospice provider can help you maximize good days at home.
Thinking About When It's Time
Deciding when to say goodbye is one of the hardest acts of love. The score is a tool to bring objectivity to an emotional decision — it does not make the decision for you.
Consistently low scores (below 35) over several days are a strong signal to talk with your vet
Consider whether your dog still experiences more good days than bad
Identify your dog's 'three things' it loves — when it can no longer do any of them, reflect
Severe uncontrolled pain or suffering can warrant a compassionate decision even at higher scores
Your veterinarian can discuss prognosis, comfort options, and a peaceful, pain-free passing
Quality-of-life scoring informs — but never replaces — a compassionate conversation with your veterinarian, who can weigh your dog's full medical picture and your family's circumstances.
Keeping a Good-Days Diary
Tracking scores over time turns a snapshot into a trend, which is far more informative than any single assessment.
Score quality of life on the same day each week (or daily near the end)
Mark each day simply as 'good' or 'bad' on a calendar
Note appetite, pain, mobility, and mood in a short journal entry
Take photos or short videos to compare how your dog moves and engages over time
Share the trend with your vet — patterns reveal what a single visit cannot

FAQs
What is the HHHHHMM quality of life scale?
HHHHHMM is a veterinarian-developed scale by Dr. Alice Villalobos that scores seven areas of a dog's well-being — Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad — each from 0 to 10. The seven scores add up to a total out of 70, giving an objective snapshot to discuss with your veterinarian.
What score means my dog has a good quality of life?
A total of 56 or above (out of 70) generally indicates a good quality of life, 35 to 55 is acceptable but worth improving, and below 35 suggests declining quality of life. Dr. Villalobos's original guideline is that a total above 35 represents an acceptable quality of life that may justify continued hospice care. Trends over time matter as much as any single score.
How often should I assess my dog's quality of life?
For a stable dog, weekly is reasonable. For a dog with a serious or progressing illness, assess every few days, and daily as the end of life approaches. Scoring on a regular schedule reveals the trend — whether your dog is improving, holding steady, or declining — which is more useful than a one-time number.
Can my dog's quality of life improve?
Often, yes. A low score frequently points to fixable problems — uncontrolled pain, poor appetite, dehydration, or mobility trouble. With veterinary support (pain control, appetite stimulants, fluids, mobility aids) and home adjustments, many dogs regain comfort and good days. Re-assess after changes to see whether the score improves.
Is this calculator a diagnosis or a decision?
No. It is a structured educational aid to help you assess your dog objectively and prepare for a conversation with your veterinarian. It does not diagnose disease and does not decide anything. Your vet knows your dog's full medical picture and can guide treatment, comfort care, and end-of-life choices.
How do I know when it's time to say goodbye?
Consistently low scores (below 35) over several days, more bad days than good, uncontrolled pain, or the loss of everything your dog enjoys are strong signals to talk with your veterinarian. There is rarely a single perfect moment; the goal is to prevent suffering and allow a peaceful, dignified passing. Your vet can help you weigh prognosis and comfort.
What is hospice or palliative care for dogs?
Hospice (sometimes called 'pawspice') and palliative care focus on comfort and dignity rather than cure. This can include pain management, anti-nausea medication, subcutaneous fluids, mobility support, and a calm home environment. A veterinary hospice provider can help you maximize your dog's good days for as long as quality of life allows.
