Dog Quality of Life Scale: The HHHHHMM Tool, and Knowing When It's Time
By Sarah Bennett · Last updated June 15, 2026 · 8 min read
Quality of life decisions are among the hardest a dog's family will ever make. They are also among the most important, and they get easier with structure.
Quick answer: The dog quality of life scale most veterinarians use is the HHHHHMM scale, created by veterinary oncologist Dr. Alice Villalobos. You score seven factors, Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad, from 0 to 10 each, for a total out of 70. A total above 35 generally means quality of life is still acceptable and supportive care can continue; a total that stays below 35 is the signal to talk with your vet about supportive or end-of-life care. A printable chart to track the score over time is at the end of this guide.
The HHHHHMM Quality of Life Scale for dogs, developed by veterinary oncologist Dr. Alice Villalobos and published in her book Canine and Feline Geriatric Oncology: Honoring the Human-Animal Bond (Wiley-Blackwell), is the most widely used tool in veterinary medicine for assessing a senior dog's quality of life. It scores seven factors on a 0-10 scale, gives families a numeric anchor for hard conversations, and replaces "I think she's okay" with "this is what I observed today."
This guide explains what each factor measures, how to score it, how to use the result, and where to download a printable version.

What the HHHHHMM Scale Measures
The HHHHHMM scale assesses seven factors. Each scores from 0 (worst) to 10 (best), so the total runs from 0 to a possible 70. The total is summed.
| Letter | Factor | Question |
|---|---|---|
| H | Hurt | Is your dog's pain managed? |
| H | Hunger | Is your dog eating enough? |
| H | Hydration | Is your dog drinking enough? |
| H | Hygiene | Can your dog stay clean? |
| H | Happiness | Does your dog still enjoy life? |
| M | Mobility | Can your dog move with reasonable comfort? |
| M | More good days than bad | Is the balance still positive? |
A total above 35 generally indicates acceptable quality of life and that palliative care through Dr. Villalobos's "Pawspice" framework can reasonably continue. A total consistently below 35 suggests that supportive or end-of-life care should be discussed with your veterinarian.
What Does HHHHHMM Stand For?
HHHHHMM is an acronym, not a typo. It stands for the seven things the scale measures: five factors that begin with H, followed by two that begin with M.
| Letters | Stands for |
|---|---|
| H, H, H, H, H | Hurt, Hunger, Hydration, Hygiene, Happiness |
| M, M | Mobility, More good days than bad |
That is five H's and two M's. The count is easy to misremember, so if you have seen it written with a different number of letters, the version above is the one Dr. Villalobos published. You will also see the same tool called the Villalobos scale, the Pawspice quality of life scale, or simply a dog quality of life chart. They all refer to this seven-factor assessment.
How to Score Each Factor
Hurt (Pain)
What it measures: Is your dog's pain managed effectively? Pain often manifests subtly in senior dogs, through reluctance to move, panting at rest, hiding, or changes in posture.
Scoring guide:
- 0 to 3: Pain is poorly controlled despite medication; visible distress most of the day
- 4 to 6: Pain is partially controlled; the dog has comfortable hours but breakthrough pain
- 7 to 10: Pain is well controlled with current management; the dog appears comfortable most of the time
What to observe today: Time spent sleeping comfortably vs. shifting position; willingness to move from a resting place; panting at rest with no obvious cause.
Hunger
What it measures: Is your dog eating enough, and willingly?
Scoring guide:
- 0 to 3: Refusing most food; weight loss; only eats with significant coaxing
- 4 to 6: Eats less than normal; selective eating; some meals refused
- 7 to 10: Eats meals consistently with reasonable interest; weight stable
What to observe today: Does your dog finish their usual portion? Do they eat unprompted, or only when offered hand-feeding?
Hydration
What it measures: Is your dog drinking enough to stay hydrated? Dehydration is a major comfort issue in senior dogs.
Scoring guide:
- 0 to 3: Refuses water; signs of dehydration (sunken eyes, skin slow to retract)
- 4 to 6: Drinks intermittently; needs encouragement or subcutaneous fluids
- 7 to 10: Drinks normally; well-hydrated skin and gums
Quick check: Gently lift the skin between the shoulder blades. If it snaps back immediately, hydration is normal. If it stays peaked, the dog is dehydrated, call your vet.
Hygiene
What it measures: Can your dog stay clean? This includes urinary and fecal continence, ability to be groomed without distress, and skin condition.
Scoring guide:
- 0 to 3: Frequent house soiling; severe matting; pressure sores; cannot reach own hindquarters
- 4 to 6: Occasional accidents; needs daily assistance with cleaning
- 7 to 10: Stays clean with minimal help; no skin issues
What to observe today: Has your dog had accidents this week? Are there areas of their body they can't reach to clean? Are pressure points developing?
Happiness
What it measures: Does your dog still respond to the things they once loved, your voice, their food, a favorite person, their ball?
Scoring guide:
- 0 to 3: Withdrawn most of the time; no response to favorite people or activities; signs of depression
- 4 to 6: Brief moments of engagement but mostly quiet or distant
- 7 to 10: Recognizable joy in daily routine, meals, walks, family interaction
What to observe today: Did your dog greet you when you came home? Did their tail move at the food bowl? Did they ask for affection?
This is the most subjective factor on the scale. Trust your read of your own dog.
Mobility
What it measures: Can your dog move with reasonable comfort? This isn't about athletic ability, it's about being able to reposition, eat, drink, and relieve themselves without significant distress.
Scoring guide:
- 0 to 3: Cannot stand or walk without help; develops pressure sores; needs to be lifted to eat or drink
- 4 to 6: Walks short distances with effort; needs help with stairs and getting up
- 7 to 10: Moves reasonably for their age; can manage daily activities with light assistance
What to observe today: Can your dog get from their bed to their water bowl unassisted? Can they change positions when uncomfortable?
More Good Days Than Bad
What it measures: Over the past week, did your dog have more good days than bad?
Scoring guide:
- 0 to 3: More bad days than good for two consecutive weeks
- 4 to 6: Roughly equal; trending toward more bad days
- 7 to 10: Noticeably more good days; bad days are exceptions
Why this factor matters most: A single bad day is normal. A sustained pattern of bad days outnumbering good ones is what Dr. Villalobos's published guidance identifies as the time to begin end-of-life conversations, this is the final "M" in the HHHHHMM scale and is widely cited in veterinary hospice literature as the most decision-relevant factor in the scale.
How to Use the Total Score
Total score 35 or above: Your dog's quality of life is in the acceptable range. Continue current care. Re-score weekly, or after any meaningful change.
Total score 30 to 34: Worth a conversation with your veterinarian about supportive care, adjusting pain medication, modifying diet, adding mobility aids, or exploring options such as acupuncture or laser therapy. Re-score every 3 to 4 days.
Total score below 30, sustained for one week or more: This is the range where families and vets commonly begin discussions about hospice care, comfort-focused medicine, and end-of-life planning. The scale itself doesn't make the decision, it provides language and structure for the conversation.
A note on individual factors: Some families consider any single factor scored at 0 to 2 to warrant immediate veterinary contact, even if the total remains above 35. A 0 on Hurt or Hunger is a more urgent signal than a 0 on Happiness.
A worked example: Say a 13-year-old dog with arthritis scores like this in a given week: Hurt 6 (managed, but stiff in the mornings), Hunger 8, Hydration 8, Hygiene 5 (an occasional accident), Happiness 7, Mobility 4 (needs help on stairs), and More good days than bad 6. The total is 44 out of 70, which sits in the acceptable range, while Mobility and Hygiene stand out as the two factors to support next, through ramps and traction, help with cleaning, and a vet conversation about pain control. Re-scoring the following week shows whether those numbers hold or slip, which is the trend that actually matters.
How to Have the Conversation With Your Vet
Bring your scored sheet to the appointment. Tell the vet you've been tracking your dog's quality of life and want to discuss the trend.
Questions worth asking:
- "Based on what you see and what I've scored, where do you think we are?"
- "What supportive options haven't we tried yet, medications, therapies, mobility aids?"
- "If we adjust [pain management / diet / environment], what change might I expect, and by when?"
- "What signs would tell me we're moving from 'manage' to 'comfort care only'?"
- "Do you offer at-home euthanasia, or can you refer me to a service that does?"
The Quality of Life Scale doesn't replace your vet's clinical judgment. It gives you both shared language.
How to Use the Scale as a Family
If multiple family members care for your dog, scoring together once a week can help align everyone on what you're seeing. Disagreements often come from different observation windows, one person sees the morning, another sees the evening.
Some families find it easier to score independently first, then compare. Others sit down together. Either works. What matters is that everyone is reading the same data.
If children are part of the family, age-appropriate honesty about what the scores mean tends to land better than protecting them from the process.

Quality of Life Scale Frequently Asked Questions
What is the quality of life scale for dogs? The Quality of Life Scale for dogs is a 7-factor scoring tool developed by veterinary oncologist Dr. Alice Villalobos. It scores Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad, each on a 0 to 10 scale, to help families and vets evaluate a senior dog's quality of life.
How do you score a dog's quality of life? Score each of the seven factors (Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, More good days than bad) from 0 (worst) to 10 (best) based on your observations. Sum the scores. A total above 35 generally indicates acceptable quality of life.
What is the HHHHHMM scale? HHHHHMM is the acronym for the seven factors in Dr. Alice Villalobos's quality of life scale for dogs and cats: Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad. That is five H's and two M's. The scale is also written as HHHHMM, HMMM, or called the H5M2 scale (shorthand for 5 H's and 2 M's). All of these refer to the same Villalobos quality of life tool.
What is a good quality of life score for a dog? The scale runs from 0 to a possible 70. A total above 35 is generally considered acceptable quality of life, meaning supportive and palliative care can reasonably continue. Scores that stay below 35, or any single factor sitting at 0 to 2, are the signals to talk with your veterinarian.
When is it time to let a dog go? There's no single threshold, but most vets consider sustained quality of life scores below 30, particularly when multiple individual factors are at 0 to 3, to be the range where end-of-life conversations should begin.
How often should I score my dog's quality of life? Weekly is reasonable for most senior dogs. Score every 3 to 4 days if your dog is in declining health. Daily if you're in active hospice care.
Should I score my dog at the same time of day? Yes. Senior dogs often have better and worse hours, especially with arthritis or cognitive issues. Scoring at the same time creates more reliable comparisons.
Is a low quality of life score for a dog enough to make a decision? No. The scale is designed to track trends. One bad day in an otherwise good week is normal. A pattern of low scores over one to two weeks is the signal worth acting on.
