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.

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). 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.

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:

0–3: Pain is poorly controlled despite medication; visible distress most of the day
4–6: Pain is partially controlled; the dog has comfortable hours but breakthrough pain
7–10: 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:

0–3: Refusing most food; weight loss; only eats with significant coaxing
4–6: Eats less than normal; selective eating; some meals refused
7–10: 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:

0–3: Refuses water; signs of dehydration (sunken eyes, skin slow to retract)
4–6: Drinks intermittently; needs encouragement or subcutaneous fluids
7–10: 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:

0–3: Frequent house soiling; severe matting; pressure sores; cannot reach own hindquarters
4–6: Occasional accidents; needs daily assistance with cleaning
7–10: 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:

0–3: Withdrawn most of the time; no response to favorite people or activities; signs of depression
4–6: Brief moments of engagement but mostly quiet or distant
7–10: 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:

0–3: Cannot stand or walk without help; develops pressure sores; needs to be lifted to eat or drink
4–6: Walks short distances with effort; needs help with stairs and getting up
7–10: 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:

0–3: More bad days than good for two consecutive weeks
4–6: Roughly equal; trending toward more bad days
7–10: Clearly 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 30–34: 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 3–4 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 0–2 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.

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 0–10 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.

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 0–3 — 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 3–4 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.
