Assess your dog's quality of life using the HHHHHMM veterinary scale. Evaluate hurt, hunger, hydration, hygiene, happiness, mobility, and more good days than bad.
Assessing quality of life in aging, chronically ill, or terminally ill dogs is one of the most difficult decisions pet owners face. The HHHHHMM Quality of Life Scale, developed by veterinary oncologist Dr. Alice Villalobos, provides a structured framework for this evaluation by scoring seven key criteria: Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More Good Days Than Bad.
Each criterion is scored from 0 (worst) to 10 (best), with a total possible score of 70. A total score above 35 generally indicates acceptable quality of life, while scores below 35 suggest quality of life is poor and humane end-of-life decisions should be discussed with your veterinarian. Individual category scores below 5 are also concerning even if the total is above 35.
This tool helps you objectively assess your dog's day-to-day experience, track changes over time, and facilitate informed conversations with your veterinarian about palliative care options or end-of-life timing. Regular reassessment (weekly or biweekly) provides a clearer picture than a single evaluation.
Emotional attachment can make it difficult to objectively assess a beloved pet's suffering. This structured scale provides consistent, measurable criteria that help separate emotional perception from observed reality, enabling better-informed decisions about your dog's care. This dog quality of life calculator helps you compare outcomes quickly and reduce avoidable mistakes when making day-to-day care decisions. Use the estimate as a planning baseline and confirm final decisions with a qualified professional when risk is high.
HHHHHMM Scale: Hurt (0-10) + Hunger (0-10) + Hydration (0-10) + Hygiene (0-10) + Happiness (0-10) + Mobility (0-10) + More Good Days Than Bad (0-10) = Total (0-70). Above 35: generally acceptable QoL. Below 35: quality of life is likely compromised. Any single category below 5: area of serious concern.
Result: Total: 44/70. Quality of life is currently acceptable but mobility is a concern (4/10). Discuss pain management options with vet.
A score of 44 is above the 35 threshold, indicating acceptable overall quality of life. However, mobility at 4/10 indicates significant difficulty. Happiness at 5/10 suggests marginal enjoyment. Focus interventions on improving mobility (pain management, physical therapy, assistive devices).
**Hurt (0-10):** Can pain be adequately controlled? Is the dog panting, whimpering, or reluctant to be touched? Adequate pain management through medication, acupuncture, or other modalities is often the most impactful intervention. **Hunger (0-10):** Is the dog eating enough to maintain body condition? Hand feeding, appetite stimulants, or feeding tubes may be options. **Hydration (0-10):** Is the dog drinking adequately? Signs of dehydration include dry gums, skin tenting, and lethargy. Subcutaneous fluids can help. **Hygiene (0-10):** Can the dog be kept clean and dry? Incontinence, pressure sores, and inability to groom significantly impact dignity and comfort. **Happiness (0-10):** Does the dog show interest in surroundings, family interaction, and previously enjoyed activities? The "light in the eyes" is an important indicator. **Mobility (0-10):** Can the dog move comfortably? Assistive devices (harnesses, carts, ramps) may help maintain independence.
The final criterion — More Good Days Than Bad — is often the tipping point for end-of-life discussions. Track each day as "good" or "bad" on a calendar. When bad days consistently outnumber good ones, or when the good days are merely "not terrible" rather than genuinely enjoyable, quality of life has likely deteriorated below an acceptable threshold.
Bring your quality-of-life assessments (with dates) to your veterinary appointment. Discuss: What is the realistic prognosis? Are there untried treatment or comfort options? What specific changes would indicate further decline? Having objective data helps both you and your vet make compassionate, informed decisions together.
Developed by Dr. Alice Villalobos (veterinary oncologist), it evaluates 7 criteria: Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More Good Days Than Bad. Each is scored 0-10, with 70 total possible. Scores above 35 indicate acceptable quality of life.
For dogs with chronic or terminal illness, weekly assessments provide the best trend data. For rapidly declining dogs, daily or every-other-day evaluations help detect changes. Keeping a written log helps identify gradual changes that might otherwise go unnoticed.
There is no single number that dictates this decision. A total below 35, or persistent scores below 5 in multiple categories, suggest poor quality of life. The decision should also consider your dog's prognosis, treatment options, and individual temperament in consultation with your vet.
Daily variation is normal, especially with chronic conditions that have good and bad days. The "More Good Days Than Bad" criterion specifically addresses this. Focus on the weekly trend rather than any single assessment.
While designed for chronically or terminally ill dogs, the scale can also help assess healthy senior dogs and identify early quality of life changes that might be addressed with medical intervention, environmental modifications, or pain management. This keeps planning practical and lowers the chance of preventable errors.
No — this is one tool among many. The scale should be used alongside veterinary guidance, your intimate knowledge of your dog's personality and normal behavior, and consideration of prognosis and available treatments. It provides structure but not the answer itself.
