Quality of Life Scale for Dogs: The HHHHHMM Assessment Explained
What the HHHHHMM Scale Measures
Dr. Alice Villalobos, a veterinary oncologist and hospice pioneer, created the HHHHHMM Quality of Life Scale to give pet owners a structured way to assess their dog's daily experience. Each letter stands for one dimension of wellbeing:
- Hurt — Is pain being managed effectively? Can your dog rest comfortably?
- Hunger — Is your dog eating enough to maintain nutrition, with or without assistance?
- Hydration — Is fluid intake adequate? Is supplemental hydration needed?
- Hygiene — Can your dog be kept clean? Are pressure sores, urine scalding, or matting present?
- Happiness — Does your dog still show interest in surroundings, family, or favorite activities?
- Mobility — Can your dog move enough to meet basic needs? Are stumbles or falls frequent?
- More Good Days Than Bad — When bad days consistently outnumber good ones, the scale signals that quality of life has dropped below an acceptable threshold.
How to Score Each Category
Rate each category from 0 to 10, where 0 is the worst possible and 10 is normal/healthy. A total score above 35 (out of 70) generally suggests acceptable quality of life. Scores at or below 35 indicate that the dog's suffering may outweigh their comfort.
| Category | Score 0–3 (Poor) | Score 4–6 (Moderate) | Score 7–10 (Good) |
|---|---|---|---|
| Hurt | Pain not controlled by medication | Managed but breakthrough pain occurs | Comfortable, breathing easily |
| Hunger | Refuses food, requires force-feeding | Eats with coaxing or hand-feeding | Eats willingly, maintains weight |
| Hydration | Severely dehydrated, requires IV fluids | Drinks with encouragement | Drinks normally |
| Hygiene | Chronic soiling, pressure sores | Needs frequent cleaning but manageable | Self-grooming or easily maintained |
| Happiness | No response to family, withdrawn | Occasional interest, mostly passive | Alert, responsive, tail wags |
| Mobility | Cannot stand or move without full support | Moves with assistance, occasional falls | Walks independently |
| More Good Than Bad | Bad days far outnumber good | Roughly equal | Mostly good days |
Why the Scale Works Better Than Instinct Alone
Most people delay the euthanasia decision because they're terrified of acting too early. Others rush because they can't bear watching decline. Both responses come from love, but they're guided by emotion rather than observation.
The scale forces you to look at seven specific, concrete measurements instead of the general sense of "they seem okay" or "they look miserable." A dog might score well on happiness and hunger but poorly on mobility and pain — that specificity helps you and your veterinarian have a grounded conversation about what's actually happening.

Tracking Changes Over Time
A single snapshot matters less than the trend. Score your dog at the same time each day — morning is usually best, before any pain medication takes effect. Write the numbers down. After a week, the trajectory becomes clear in a way that day-to-day observation obscures.
If scores are declining steadily, even by a point or two per week, that pattern tells you something important. If scores fluctuate wildly — a 42 one day, a 28 the next — that instability itself is a sign of diminishing quality of life.
Having the Conversation With Your Vet
Bring your scored sheets to the appointment. Veterinarians respect families who've done this work because it moves the conversation past "what do you think I should do?" into specific clinical territory. Your vet can address the low-scoring categories directly: can we try a different pain protocol? Would a mobility aid help? Is the hunger issue treatable or a sign of systemic decline?
The decision is never clean. There's no score that removes the grief. But the scale gives you evidence that you made the call based on your dog's experience, not your own fear — and that matters enormously in the weeks and months after.
When the Scale Points Toward Euthanasia
A consistent total at or below 35 is a reason to discuss your dog's quality of life and options with your veterinarian; the scale is a discussion aid, not a standalone euthanasia decision. The hardest version is when hunger and happiness are still moderate but pain and mobility have collapsed — your dog still wants to be here, but their body is failing them.
In-home euthanasia services (typically $250–$500) allow the procedure in familiar surroundings, which many families find less traumatic for both the dog and themselves.
