Glasgow Pain Score Calculator
Assess your dog's pain level using the Glasgow Composite Pain Scale. Score behavioral indicators to determine severity and know when to seek vet care.
Start AssessmentOne of the hardest parts of caring for an elderly, seriously ill, or hospice-stage dog is separating hope, fear, and daily reality. The Dog Quality of Life Calculator uses the HHHHHMM scale (Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, More good days than bad), developed by Dr. Alice Villalobos, to turn home observations into a structured score. The result does not make a decision for you. It helps you notice patterns, identify the lowest areas, and prepare a clearer conversation with your veterinarian.
The HHHHHMM Quality of Life Scale
Each of the seven dimensions is scored from 0 (worst possible) to 10 (best possible), for a maximum score of 70. The original scale commonly treats a total above 35 as acceptable for supportive care, but the total is not the whole story. A very low score in pain, hydration, mobility, or hygiene can deserve urgent attention even when the total is higher.
| Dimension | Score 0-2 (Urgent concern) | Score 3-6 (Needs support) | Score 7-10 (More stable) | What to ask your vet |
|---|---|---|---|---|
| H - Hurt | Severe pain, labored breathing, or distress | Pain partly controlled, breakthrough discomfort, restlessness | Comfortable breathing and pain appears managed | Can pain control or breathing support be improved? |
| H - Hunger | Refuses food or cannot eat | Eats only with coaxing, hand-feeding, appetite support, or treats | Eats enough and still shows interest in meals | Could nausea, dental pain, medication, or disease be affecting appetite? |
| H - Hydration | Not drinking, dehydrated, or unable to keep fluids down | Needs encouragement, monitoring, or supplemental fluids | Drinks normally with moist gums and normal urination | Are fluids, lab work, or dehydration treatment needed? |
| H - Hygiene | Cannot be kept clean, has sores, or remains wet/soiled | Needs frequent cleaning, bedding changes, diapers, or coat care | Clean, dry, odor-free, and free of pressure sores | How can we prevent sores, infection, and discomfort? |
| H - Happiness | Withdrawn, fearful, confused, or no longer responds | Some interest, but less social response or fewer good moments | Responsive, engaged, and still enjoys familiar routines | Is pain, anxiety, cognition, or medication affecting mood? |
| M - Mobility | Cannot rise or move without major distress | Limited movement; needs help, harnesses, ramps, or non-slip surfaces | Moves independently or with minor support | Would pain treatment, assistive gear, or home changes help? |
| M - More good days than bad | Bad days dominate | Good and bad days are mixed or unpredictable | Good days clearly outnumber bad days | What trend should trigger another care or hospice discussion? |
Interpreting the Total Score
Use the total as a conversation aid, then look at the lowest individual categories.
| Total Score | Interpretation | Recommended Approach |
|---|---|---|
| 56-70 | Strong quality-of-life picture | Continue current care and reassess on a regular schedule |
| 42-55 | Generally acceptable quality of life | Monitor trends and ask about small improvements in the lowest areas |
| 36-41 | Borderline quality-of-life picture | Plan a veterinary conversation soon; category lows matter here |
| 28-35 | Poor to marginal quality of life | Discuss palliative care, prognosis, comfort goals, and timing |
| 14-27 | Very poor quality-of-life picture | Prompt hospice or euthanasia conversation is appropriate if not rapidly improvable |
| 0-13 | Critical concern | Seek urgent veterinary guidance, especially after a sudden decline |
How to Use the Result
Use the same observation window each time, such as the past week or the past 1-2 weeks. Record the score, the lowest categories, and one sentence about what changed. If several family members disagree, have each person score independently and compare the lowest areas rather than arguing over the final number.
The calculator stores recent scores only in this browser so you can compare short-term trends. Downloading or copying the vet summary can help you bring the same facts to an appointment.
Other Quality of Life Assessment Tools
Different tools answer different questions. They can complement, not replace, veterinary judgment.
| Tool | What It Measures | Best Use |
|---|---|---|
| HHHHHMM Scale | Pain, appetite, hydration, hygiene, happiness, mobility, and good days | General hospice and end-of-life quality-of-life review |
| Lap of Love Daily Assessment | Mobility, nutrition, hydration, interaction, elimination, and favorite things | Simple daily tracking and trend notes |
| Glasgow Composite Pain Scale | Visible pain-related behaviors | When pain is the main concern |
| Canine cognitive dysfunction tools | Disorientation, sleep, house soiling, anxiety, and interaction changes | When dementia-like changes are part of the picture |
Talking to Your Veterinarian About Quality of Life
Bring the completed score, the lowest categories, and examples from home. Useful questions include: "Is my dog in pain that can be better controlled?", "Which low scores are medically improvable?", "What changes should I expect over the next 2-4 weeks?", and "What signs would mean we should not wait?" These direct questions make the conversation clearer when emotions are high.
Frequently Asked Questions
How do I know if my dog is in pain?
Common pain signs include reluctance to rise, stiffness, panting at rest, restlessness, trembling, guarding part of the body, reduced appetite, changed sleep, hiding, and less interest in family routines. Trouble breathing or uncontrolled pain should be treated as urgent.
What if the total is above 35 but one category is very low?
Do not ignore the low category. The original HHHHHMM threshold is a useful guide, but a dog with severe pain, dehydration, inability to move, or hygiene problems may need prompt help even if other categories still score well.
How often should I repeat the quality-of-life score?
For a stable senior dog, monthly scoring may be enough. For chronic illness, weekly scoring is often more useful. For hospice or a rapidly changing condition, daily notes or every-few-day scoring may help you and your veterinarian see the trend.
Is it wrong to consider euthanasia before a dog stops eating?
No. Appetite is only one part of quality of life, and complete food refusal can be a late sign. Pain, breathing distress, inability to rest, repeated bad days, and loss of comfort can all matter before a dog stops eating entirely.
Can a quality-of-life score improve?
Sometimes. Pain control, anti-nausea care, appetite support, hydration support, non-slip flooring, harnesses, bedding changes, grooming, and anxiety or dementia support can improve specific categories. The lowest scores show where to ask first.
Note: Quality of life scores are a support tool for reflection and discussion, not a replacement for professional guidance.
