Veterinarian Dr. Alice Villalobos, a pioneer of pet hospice care, created the HHHHHMM scale to help families and vets talk about quality of life as dogs age or face serious illness.1,2 Each category is scored 0–10, where 10 is ideal.2

CategoryAsk yourself
HurtIs pain controlled? Can they breathe comfortably? Trouble breathing outweighs everything else.
HungerAre they eating enough? Does hand-feeding help?
HydrationAre they drinking enough, or do they need fluids?
HygieneCan they stay clean? Are sores or soiling under control?
HappinessDo they show joy and interest, or seem anxious, bored or afraid?
MobilityCan they get up without help? Any falls or stumbling?
More good days than badWhen bad days outnumber good ones, quality of life may be too compromised.

In Dr. Villalobos’s framework, a total above 35 (out of 70) represents acceptable quality of life for continuing comfort-focused care.2 She also notes that more than 3–5 bad days in a row tends to go along with a score below 35.1

Use it for trends, not verdicts

The senior care guidelines point out that most online quality-of-life scales haven’t been scientifically validated,3 and Dr. Villalobos says the same about research in this area.1 The most useful thing is doing it regularly and bringing the history to your vet. The guidelines also suggest marking good and bad days on a calendar.3
