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 most difficult decisions any pet owner faces is assessing when a seriously ill or elderly dog's quality of life has diminished to the point where euthanasia should be considered. The Dog Quality of Life Calculator uses the veterinary validated HHHHHMM scale (Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, More good days than bad), developed by Dr. Alice Villalobos, to provide a structured, objective way to assess your dog's quality of life score. This tool does not make the decision for you - it gives you language and structure for a conversation that is among the most important you will ever have.
The HHHHHMM Quality of Life Scale
Each of the seven dimensions is scored from 1 (worst) to 10 (best). A total score above 35 is generally considered acceptable quality of life. This is a guide, not a verdict.
| Dimension | Score 1-3 (Poor) | Score 4-6 (Moderate) | Score 7-10 (Good) | Questions to Ask |
|---|---|---|---|---|
| H - Hurt | Pain is severe and uncontrolled; labored breathing | Pain is present but partially managed; some distress | Pain well controlled; comfortable breathing | Is the pain managed? Is the dog able to breathe easily? |
| H - Hunger | Not eating; significant weight loss; too weak to eat | Eating poorly; weight loss present but eating some | Eating well; maintaining weight; enjoying meals | Is the dog eating enough to maintain acceptable body condition? |
| H - Hydration | Severely dehydrated; not drinking | Mild-moderate dehydration managed with IV fluids | Drinking well; good skin turgor; moist gums | Is the dog drinking adequately? Are fluids needed? |
| H - Hygiene | Unable to be kept clean; pressure sores; foul odor | Needs regular assistance; some skin or coat issues | Clean, well-groomed; no sores; cared-for appearance | Can the pet be kept clean and odor-free with manageable care? |
| H - Happiness | Withdrawn, disoriented, unaware; no interest in life | Some interest in surroundings; occasional response | Alert, interested; responds to family; expresses joy | Is the dog mentally aware? Do they still respond to loved ones? |
| M - Mobility | Cannot stand or walk; no bladder/bowel control | Assisted mobility; occasional accidents | Able to move with some help or independently | Can the dog get up and move? Can elimination be managed? |
| M - More good days than bad | More bad days; suffering predominates | Roughly balanced; some good moments | Clearly more good days; moments of joy | Overall, is the dog having more good days than bad recently? |
Interpreting the Total Score
Use the table below to compare Interpreting the Total Score.
| Total Score | Interpretation | Recommended Approach |
|---|---|---|
| 35-70 | Acceptable quality of life | Continue current care; reassess regularly; increase supportive care where possible |
| 25-34 | Marginal quality of life | Consult with veterinarian; review pain management; discuss prognosis honestly; reassess weekly |
| 15-24 | Poor quality of life | Serious conversation about euthanasia indicated; discuss timing with vet and family; do not delay this conversation |
| Below 15 | Very poor quality of life; significant suffering likely | Euthanasia is likely the most compassionate option; consult your vet |

Talking to Your Veterinarian About Quality of Life
Bring the completed quality of life score to your veterinary appointment. This gives your vet objective documentation of your observations and ensures nothing is glossed over in an emotional conversation. Ask explicitly: 'Is my dog in pain that cannot be further controlled?' and 'What does the medical prognosis look like over the next 2-4 weeks?' These direct questions give you the information needed to make a compassionate decision.
Frequently Asked Questions
How do I know if my dog is in pain?
Dogs hide pain instinctively. Reliable signs of chronic pain include: reluctance to get up or move, changed facial expression (ears back, tense brow, squinted eyes), reduced interaction with family, loss of interest in food or play, licking or biting at a specific body area, restlessness at night, and changes in posture (hunched, tucked, or guarded). The Feline and Canine Grimace Scale tools can also help assess pain through facial action coding.
Is it wrong to consider euthanasia before a dog stops eating?
No. Waiting until a dog stops eating entirely as the marker for euthanasia often means the dog suffers longer than necessary. Cessation of eating is a late-stage sign of declining quality of life, not the first indicator. The quality of life assessment covers many dimensions beyond food intake. Euthanasia before a pet reaches end-stage physical collapse is widely considered an act of love, not abandonment.
How do I cope after losing a dog?
Pet loss grief is real, profound, and deserves to be treated as such. Allow yourself to grieve fully. Seek support from others who understand animal bonds. Consider a pet loss support group (many humane societies and veterinary schools offer them). Give yourself time before making decisions about future pets.
Note: Quality of life scores are a support tool for reflection and discussion, not a replacement for professional guidance.
