When your pet is declining and you cannot tell if today is a bad day or the beginning of the end, you need something more structured than your feelings. The HHHHHMM Quality of Life Scale was designed for exactly this moment.

Created by Dr. Alice Villalobos, a veterinary oncologist who spent decades working with terminally ill animals, the scale measures seven dimensions of your pet's daily experience. Each dimension is scored from 0 (worst) to 10 (best). A total score below 35 out of 70 generally suggests the animal's quality of life is no longer acceptable.

But the number is not the point. The point is that the scale forces you to look at your pet's actual experience instead of your hope for what their experience might be.

Here are the seven dimensions:

**Hurt (0-10).** Is your pet in pain? Can the pain be managed with medication? A score of 0 means uncontrollable pain. A 10 means no pain at all. Be honest: if your pet flinches when touched, avoids movement, pants at rest, or vocalizes without obvious cause, pain is present. Adequate pain management through medication can keep this score higher, but if the medication stops working or causes its own problems, the score drops.

**Hunger (0-10).** Is your pet eating? Not just accepting food placed in their mouth, but actively seeking it. A pet who eats a few bites when hand-fed is not a pet with a healthy appetite. A score of 0 means they refuse all food. A 10 means normal appetite. Pay attention to the trend, not just today. Three days of declining intake matters more than one bad meal.

**Hydration (0-10).** Is your pet drinking enough water? Dehydration accelerates decline in every other category. Signs of dehydration include dry gums, sunken eyes, and skin that does not snap back when gently pinched. Subcutaneous fluids from your vet can help temporarily, but the need for them is itself a signal.

**Hygiene (0-10).** Can your pet keep themselves clean? Are they lying in their own waste? Do they have pressure sores from inability to move? A pet who can no longer groom, who develops matted fur over wounds, or who cannot get up to relieve themselves has lost a fundamental dignity. This dimension is often the one people underweight because it feels less urgent than pain — but it matters.

**Happiness (0-10).** Does your pet still respond to your presence? Do they show interest in anything — a toy, a window, a walk, another animal? A score of 0 means complete withdrawal. A 10 means normal engagement with life. This is the hardest dimension to score honestly because we want to see happiness. A single tail wag in a day of lethargy is not a 5. It is a 1 or a 2.

**Mobility (0-10).** Can your pet move on their own? Can they stand, walk, reposition themselves? A pet who cannot get up without help, who falls when trying to walk, or who can no longer reach their food or water bowl has lost a basic function. Mobility aids can help, but if the pet resists them or shows distress when moved, the score should reflect that.

**More Good Days Than Bad (0-10).** This is the summary dimension. When the bad days outnumber the good ones, the overall trajectory is clear. Keep a simple log — even just a daily mark of good or bad — so that you have data instead of just impressions. Grief distorts memory. A written record does not.

Add the seven scores together. A total of 35 or above generally suggests adequate quality of life. Below 35 suggests it is time to have the conversation with your vet.

But here is what the scale cannot tell you: when. The scale tells you where your pet is right now. It does not predict how fast the decline will happen. Some animals hold at a 30 for weeks. Others drop from 40 to 20 in three days.

Use the scale daily or every few days. Track the scores. Show them to your vet. The trend matters more than any single number. A pet who scored 45 last week and 32 this week is on a trajectory that the numbers make visible even when your heart wants to deny it.

The scale is not a permission slip. You do not need a number to validate your decision. But it can cut through the fog of emotion and show you what is actually happening in your pet's body, day by day.

If you want to track these scores over time, Threshold has a built-in quality of life tracker in your pet's companion space. It will not tell you what to decide. But it will help you see clearly when clarity feels impossible.
