Quality of Life Scale for Dogs: The HHHHHMM Assessment

Owners of senior dogs eventually face a question with no formula. The HHHHHMM scale, developed by veterinary oncologist Dr Alice Villalobos, gives it a structure. Score each item from 0 to 10, where 10 is ideal, once a week, and write the numbers down. A total above 35 is generally considered an acceptable quality of life; the trend matters more than any single score.

The seven items

Hurt. Is pain controlled? Is breathing easy? Breathing difficulty is a pain of its own and outranks everything else. Ask your vet directly whether the current medication is enough and what the next step would be.

Hunger. Is the dog eating enough by itself? Hand feeding, warming food and appetite stimulants count as help; a feeding tube is a conversation.

Hydration. Is the dog drinking, or being given fluids under the skin? Are the gums moist?

Hygiene. Can the dog be kept clean and dry? Pressure sores, urine scald and matted coat are painful and preventable with bedding changes, cleaning and grooming.

Happiness. Does the dog express joy? Interest in you, in food, in going out, in a favorite toy. Is the dog depressed, anxious or withdrawn? Can the bed be moved to where the family is?

Mobility. Can the dog get up without help, walk to relieve itself, and move around the house? Ramps, slings, harnesses and carts help. A dog that needs to be carried out to toilet can still have good days, but it is a marker.

More good days than bad. When the bad days outnumber the good in a week, quality of life is compromised. A bad day is one of pain, nausea, frustration or distress.

Using the score

• Score weekly on the same day, in the same way, and keep it where you can see the trend.
• Involve everyone in the household; different people notice different things.
• Share the scores with your vet. They turn “she seems a bit off” into something a clinician can act on, often with a medication change that raises the score again.
• Decide in advance what your lines are, while things are stable. Decisions made in a crisis at 2 a.m. are the ones people regret.

What the scale is for

It is not a countdown. Most weeks, for most dogs, it shows what to fix: pain control, a ramp, a diet change, a different bed. It becomes a decision tool only when the fixes stop working. Used honestly, it protects the dog from suffering and the owner from second-guessing.
