HHHHHMM Calculator: What the Scale Measures

This HHHHHMM calculator is based on the HHHHHMM quality of life scale developed by veterinary oncologist Dr. Alice Villalobos. HHHHHMM is an acronym for the seven factors it scores, each from 1 to 10:

  • Hurt: is pain well controlled, and can your dog breathe comfortably?
  • Hunger: is your dog eating enough, with or without help?
  • Hydration: is your dog drinking and staying hydrated?
  • Hygiene: can your dog be kept clean and free of sores?
  • Happiness: does your dog still show interest, joy, and engagement?
  • Mobility: can your dog move around, get up, and go outside?
  • More good days than bad: are the good days outnumbering the bad?

Add the seven scores for a total out of 70. A total above 35 suggests quality of life is still acceptable, while a score of 35 or below is a signal to talk with your veterinarian. Enter your scores in the calculator above to get an instant total and guidance.

FAQs

Frequently Asked Questions

What is the HHHHHMM quality of life scale?

The HHHHHMM scale (developed by Dr. Alice Villalobos) assesses seven factors: Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad. Each is scored 1-10. A total of 35 or below may indicate poor quality of life; 50+ suggests reasonable quality. Always discuss with your veterinarian.

When should I use a dog quality of life calculator?

Use this calculator for senior dogs, dogs with chronic illness, or when facing difficult care decisions. It helps you objectively assess well-being and identify areas needing attention. It's a screening tool—not a substitute for veterinary advice.

What does a low quality of life score mean?

A score of 35 or below suggests significant quality of life concerns. Discuss pain management, palliative care, and care options with your veterinarian. One severe symptom (e.g., unmanaged pain) can significantly impact quality of life even if other factors score well.

Is this the same as the Ohio State quality of life scale?

Our calculator uses the HHHHHMM scale. The Ohio State scale uses a different format (23 criteria, 1-5 ratings). Both are validated tools. The HHHHHMM scale is widely used and easier to complete. Discuss results with your vet regardless of which tool you use.
