🐾 Dog Quality of Life Calculator (Paw Score)
Rate your dog across 7 areas of wellbeing with this free Paw Score calculator. Based on the HHHHHMM Scale used by veterinary professionals to assess quality of life in senior and ill dogs.
For each category, choose the score that best describes your dog today. There are no right or wrong answers — honest observation is what matters.
What Is the Paw Score (HHHHHMM Scale)?
The HHHHHMM Scale was developed by Dr. Alice Villalobos, a veterinary oncologist, as a practical framework for pet owners and veterinarians to evaluate quality of life in dogs facing serious illness, chronic pain, or end-of-life conditions. The acronym stands for Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad.
Each category is scored from 1 to 10, for a maximum total of 70. A score of 35 or above is generally considered an acceptable quality of life — meaning most needs are being met and the dog has more positive experiences than suffering. Below 35, the balance tips, and the conversation about what more can be done — or whether continuing treatment is in the dog's best interest — becomes necessary.
It's important to understand what this scale is and isn't. It's a structured way to observe and communicate — not a verdict. A score of 32 today doesn't mean anything by itself. A score of 32 that was 45 six months ago, after declining slowly, means something different from a score of 32 that has been stable for a year.
When to Use a Quality of Life Assessment
Quality of life assessment is most useful in these situations:
Senior dogs (7+ years for large breeds, 10+ for small breeds): A monthly assessment helps you notice gradual changes before they become obvious. Aging dogs change slowly — the rib test, the stairs, the greeting at the door — and a structured checklist catches drift that day-to-day observation misses.
Dogs with terminal diagnosis: Cancer, advanced organ disease, and other terminal conditions require ongoing monitoring of wellbeing. Tracking scores monthly or weekly gives you and your vet a shared framework for decisions about treatment continuation, palliative care, or end-of-life planning.
Dogs with chronic pain conditions: Arthritis, degenerative disc disease, and other painful conditions that are managed (but not cured) benefit from regular reassessment. A pain management protocol that was working at a 7 in the Hurt category six months ago may have shifted to a 4 — that's actionable information for your vet.
Before and after treatment changes: Starting a new medication, adjusting a dose, or beginning palliative care? Assess before and assess a month later. The numbers make it easier to evaluate whether the change made a real difference.
The Hardest Question: More Good Days Than Bad
Of all seven categories, "More Good Days Than Bad" is the one that carries the most emotional weight — and often the most diagnostic value. It's also the one most owners find hardest to answer honestly.
A "good day" for a dog doesn't require a walk in the park or a game of fetch. It might mean eating breakfast with some enthusiasm, wagging when you walk in, resting comfortably without panting, or spending time near the family. A "bad day" is one where those moments are absent — replaced by visible distress, disorientation, refusing food, or obvious discomfort that can't be relieved.
Keeping a simple daily log — just one or two words — helps. "Good," "OK," "rough" is enough. After a month, the pattern is usually clear in a way that memory alone isn't.
Frequently Asked Questions
What is the Paw Score for dogs?
The Paw Score (also called HHHHHMM Scale) is a quality of life assessment tool developed by veterinary oncologist Dr. Alice Villalobos. It evaluates a dog's wellbeing across 7 categories: Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad. Each category is scored 1–10, and a total score of 35 or above is generally considered acceptable quality of life.
When should I use a quality of life calculator for my dog?
Quality of life assessments are most useful for senior dogs, dogs with terminal illness, cancer, or chronic pain conditions, or any dog whose daily wellbeing you're monitoring over time. Many vets recommend completing an assessment monthly and tracking the trend — a gradual decline over several months tells a clearer story than any single score.
What score indicates a good quality of life for a dog?
On the HHHHHMM Scale (maximum score 70), a total of 35 or above is generally considered acceptable quality of life. However, the score is a starting point for a conversation with your vet — not a definitive answer. Trends over time matter more than a single number, and some categories (especially pain/hurt) carry more weight than others.
