Dog Quality of Life Calculator

About the Dog Quality of Life Calculator

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 calculator 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.

When This Page Helps

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.

How to Use the Inputs

1. Rate each of the 7 quality of life categories from 0-10
2. Use the descriptive anchors for each score level
3. Consider your dog's typical day, not just their best moment
4. Review the total score and interpretation
5. Note any individual categories scoring below 5
6. Repeat the assessment weekly for trend tracking
7. Share results with your veterinarian for collaborative decision-making

Example Calculation

Tips & Best Practices

• Assess at the same time each day for consistency
• Keep a written log to track trends over weeks
• Have multiple family members score independently and compare
• Focus on your dog's typical day, not their best moment
• Remember that dogs are stoic — they often hide pain
• Individual scores below 5 need veterinary attention regardless of total

Understanding Each HHHHHMM Category

**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.

When "More Bad Days Than Good"

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.

Having the Conversation with Your Vet

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.

Frequently Asked Questions

• What is the HHHHHMM quality of life scale?

  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.

• How often should I assess my dog's 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.

• What score means it's time to consider euthanasia?

  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.

• Why is my dog's score different day-to-day?

  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.

• Can this scale be used for any age dog?

  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.

• Should end-of-life decisions be based solely on this score?

  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.
