Dog Quality of Life Calculator
Calculate dog quality life with our free science calculator. Uses standard scientific formulas with unit conversions and explanations.
Formula
QoL Score = Pain + Hunger + Hydration + Hygiene + Happiness + Mobility + More Good Days (each 1-10)
The HHHHHMM Quality of Life Scale by Dr. Alice Villalobos scores seven categories from 1-10, totaling a maximum of 70 points. Scores above 35 generally indicate acceptable quality of life. Scores at or below 35 suggest quality of life is compromised and end-of-life discussions with a veterinarian are recommended. The scale provides an objective framework for one of the most difficult decisions pet owners face.
Frequently Asked Questions
What is the HHHHHMM quality of life scale?
The HHHHHMM scale was developed by Dr. Alice Villalobos, a veterinary oncologist and pioneer in pet hospice care. HHHHHMM stands for Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More Good Days Than Bad. Each criterion is scored from 1 (very poor) to 10 (excellent), giving a total score out of 70. Scores above 35 generally indicate an acceptable quality of life, while scores below 35 suggest that the animal may be suffering and end-of-life decisions should be considered. This scale helps pet owners and veterinarians have objective conversations about a pet well-being.
How do I score pain management for my dog?
Score 10 if your dog shows no signs of pain and is comfortable. Score 7-9 if pain is well-controlled with medication and your dog seems mostly comfortable. Score 4-6 if pain is present but partially managed, with some panting, restlessness, or reluctance to move. Score 1-3 if your dog is in significant uncontrolled pain despite medication, showing signs like constant panting, whimpering, inability to sleep, guarding body parts, aggression when touched, or complete withdrawal. Signs of pain in dogs include changes in posture, facial expression (squinted eyes, flat ears), reduced activity, and changes in behavior or temperament.
When should I consider end-of-life decisions for my dog?
This is one of the most difficult decisions a pet owner faces. The quality of life scale provides objective data to help. Generally, if the total score falls consistently below 35, or if multiple categories score below 5, quality of life is significantly compromised. Other important indicators include: more bad days than good, inability to eat or drink for extended periods, uncontrollable pain despite maximum medication, complete loss of mobility or continence, no longer recognizing family members, or having a terminal diagnosis with rapidly declining condition. Many veterinarians recommend tracking scores over days or weeks rather than making decisions based on a single assessment.
How often should I assess my dog quality of life?
For dogs with chronic illness, cancer, or age-related decline, it is recommended to complete the quality of life assessment at least weekly, and ideally every few days during periods of change. Keep a written log or journal with dates and scores so you can track trends over time. This longitudinal view is much more valuable than any single assessment. Some veterinarians recommend that all family members complete the assessment independently to get multiple perspectives, as we can sometimes be in denial about our pet condition. Share these records with your veterinarian at each visit to guide treatment decisions together.
What can I do to improve my dog quality of life score?
For Pain: Work with your vet on multimodal pain management including medications (NSAIDs, gabapentin, tramadol), acupuncture, laser therapy, and massage. For Hunger/Hydration: Offer high-value foods, warm the food, try hand-feeding, add broth for hydration. For Hygiene: Regular grooming, protective bedding, clean wounds and incontinence promptly to prevent sores. For Happiness: Maintain social interaction, gentle play, mental stimulation through sniff walks. For Mobility: Ramps, supportive harnesses, non-slip surfaces, physical therapy, swimming. The goal is to maximize comfort and enjoyment in whatever time remains.
