What is the quality-of-life scale for dogs?

It's a simple scoring tool — often called the HHHHHMM scale — that rates seven parts of a dog's life (Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad) from 0 to 10. Adding them up gives you a calmer, more objective read on how your dog is really doing than day-to-day emotion alone.

What score means a dog still has good quality of life?

On the common 0–70 scale, a total above about 35 — with most categories scored 5 or higher — generally suggests acceptable quality of life worth supporting. But the number is a guide for a conversation with your vet, not a verdict on its own.

How often should I score my dog's quality of life?

Weekly is a good rhythm for a declining senior, or daily during a rough patch. Tracking the trend over time is far more telling than any single day's score.

The Quality-of-Life Scale for Dogs: A Gentle, Practical Guide

Few things are harder than trying to judge, through love and worry, how your old dog is actually doing. On a good afternoon you’re sure they’re fine; on a bad morning you fear the worst. A quality-of-life scale won’t make the feelings easier, but it gives you something steadier to hold onto. The most widely used tool is the HHHHHMM scale — seven areas scored 0 to 10 — and it turns a swirl of emotion into a clear, trackable picture you can revisit and share with your vet.

I’m a dog owner who has leaned on this scale through a dog’s final chapter, not your veterinarian. This is a framework for reflection and for talking with your vet — it is not medical advice and never makes the decision for you.

The HHHHHMM scale

Dr. Alice Villalobos created this scale to help families think clearly. Score each area from 0 (very poor) to 10 (excellent):

Letter	Area	Ask yourself
H	Hurt	Is pain well controlled? Can they breathe comfortably?
H	Hunger	Are they eating enough, willingly?
H	Hydration	Are they drinking (or getting fluids) enough?
H	Hygiene	Can they stay clean and dry, free of sores?
H	Happiness	Do they still show joy, interest, response to you?
M	Mobility	Can they move enough to meet their needs, with help if needed?
M	More good days than bad	Over the week, which way does it tip?

Add the seven scores for a total out of 70.

Reading the number — gently

A total above about 35, with most areas at 5 or higher, generally suggests a quality of life still worth supporting. As scores slip below that — or as any one area (often Hurt or Happiness) drops low and stays there — it’s a sign to talk with your vet about what more can be done, or about what’s kind.

But please hold the number loosely. It’s not a pass/fail. Its real gift is twofold: it makes you look honestly at the areas love tends to gloss over (like pain and hygiene), and tracked over weeks, it shows you the trend — which is what actually matters.

How to use it well

Score the week, not the moment. One great hour doesn’t erase three hard days, and one bad morning doesn’t define a good week.
Write it down. A weekly total in a notebook or phone note makes the direction unmistakable.
Involve the household. Everyone who loves the dog sees different things; compare notes.
Bring it to your vet. “His Hurt and Mobility have dropped from 7 to 3 over a month” is a conversation your vet can truly help with.

A kinder way to think about it

The point of the scale isn’t to brace for the worst — it’s to make sure your dog’s good days stay genuinely good. Low scores are often a prompt to fix something: better pain control, softer bedding, a lift harness for mobility, or gentle enrichment for happiness. Many families find that scoring honestly leads first to changes that lift the numbers back up.

The bottom line

Your dog can’t tell you how they feel, so a simple weekly score is one of the most loving tools you have. Use the HHHHHMM scale to stay honest, track the trend, and open a clear-eyed conversation with your vet — not to carry the weight of the decision alone, but to make sure your dog’s remaining time is as comfortable and joyful as you can make it.
