What is the HHHHHMM Quality of Life Scale?
The HHHHHMM Scale evaluates 7 clinical criteria scored 0–10: Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More Good Days than Bad Days. A total score of 35 or above indicates acceptable quality of life.
| Category / Metric | Clinical Benchmark | Veterinary Guidance |
|---|---|---|
| Score 35 – 70 | Acceptable Quality of Life | Continue current palliative plan |
| Score 20 – 34 | Declining Health | Consult vet for pain/symptom adjustment |
| Score < 20 | Severe Suffering | Discuss peaceful end-of-life transition |
Most pet owners don’t start thinking about a pet quality of life scale when their animal is healthy. This framework tends to arrive in your life when you’re already facing the hardest part of caregiving: watching a dog slow down, a cat withdraw, or a companion who used to bound toward the door now barely lifting their head.
This pet quality of life checklist serves as a structured veterinary assessment tool to evaluate your dog’s or cat’s physical comfort and well-being across specific, measurable domains. Instead of relying on gut feeling alone (which grief and love can easily distort in both directions), it allows you to score each domain from 1 to 10, track those scores weekly, and build a trend line that reveals what is actually happening over time.
The most widely used clinical framework is the HHHHHMM scale, developed by veterinary oncologist Dr. Alice Villalobos and first published in Veterinary Practice News in 2004. It was designed specifically for dogs and cats in palliative and end-of-life care, and it remains the standard framework used by veterinary teams and pet hospice organizations today. Whether your companion is a senior Labrador with arthritis or a 15-year-old tabby managing kidney disease, a pet quality of life checklist gives you the language to name what you observe – and a structure for making decisions without second-guessing yourself into paralysis.

Senior Pet Quality of Life Report
| Domain | Score | Observed Criteria / Comfort Indicators |
|---|
Clinical Foundation: The HHHHHMM scale was developed by Dr. Alice Villalobos, DVM, DPNAP, as a framework for Pawspice (pet hospice) care. Each domain is scored from 1 (worst) to 10 (best). Total scores of 50-70 indicate an acceptable quality of life; 35-49 indicate declining quality of life requiring prompt veterinary consultation; and scores under 35 indicate a critical state requiring immediate veterinary support.
The HHHHHMM & Lap of Love Quality of Life Assessment Matrix
Developed by veterinary oncologist Dr. Alice Villalobos and endorsed by pet hospice providers (including Lap of Love), the HHHHHMM scale evaluates seven clinical domains on a 0–10 point scale (0 = worst, 10 = best). A total score above 35 points generally indicates an acceptable quality of life with proper hospice support:
| Domain | Score (0–10) | Clinical Evaluation Criteria | Target Threshold |
|---|---|---|---|
| 1. Hurt (Pain Control) | 0 – 10 | Is pain effectively managed? Are breathing and oxygen levels normal? (Pant rate <30 breaths/min at rest; no vocalizing, shaking, or guarding). | Score ≥ 5: Pain well-controlled with medication |
| 2. Hunger (Nutrition) | 0 – 10 | Is your pet eating voluntarily? Do they require hand-feeding, warm food, or appetite stimulants (e.g. Entyce / mirtazapine)? | Score ≥ 5: Consuming ≥75% daily caloric need |
| 3. Hydration | 0 – 10 | Are skin turgor and gums moist? Does your pet drink independently, or do they need daily sub-Q (subcutaneous) fluids? | Score ≥ 5: Normal hydration without fluid debt |
| 4. Hygiene | 0 – 10 | Can your pet groom and remain clean after elimination? Are pressure sores, urine scald, or fecal soiling prevented? | Score ≥ 5: Clean coat, dry skin, no bedsores |
| 5. Happiness | 0 – 10 | Does your pet express joy, wag their tail, purr, interact with family, or respond to favorite toys? Are they mentally alert vs isolated/depressed? | Score ≥ 5: Engaged with household life |
| 6. Mobility | 0 – 10 | Can your pet stand, walk outside to relieve themselves, or change resting positions independently or with a supportive harness/ramp? | Score ≥ 5: Can posture and reposition comfortably |
| 7. More Good Days Than Bad | 0 – 10 | Do comfortable, peaceful days outnumber days dominated by nausea, pain, disorientation, or distress? | Score ≥ 5: Clear majority of days are positive |
| Total HHHHHMM Score | / 70 Points | >35 = Acceptable Quality of Life | <35 = Palliative / Euthanasia Review Recommended | |
