One of the most common sentences I hear as an in-home hospice veterinarian on Long Island is, “I just don’t know if he’s suffering.” It is an honest, loving question, and for most families it is very hard to answer from inside the house where the decline is happening slowly, day by day. The HHHHHMM quality of life scale for dogs and cats was designed for exactly that reason to give families a gentle, structured way to see their pet honestly.
This post walks through each of the seven categories, how to score your pet, and how to track the numbers over time. I’m Dr. Jake Labriola, founder of Calm Paws Vet, and I use this quality of life scale for dogs and cats every week with families across East Setauket, Stony Brook, Port Jefferson, and the broader North Shore.
Where the Scale Comes From
The HHHHHMM Quality of Life Scale was developed by veterinary oncologist Dr. Alice Villalobos, one of the pioneers of the animal hospice movement. It is widely used by hospice-trained veterinarians and is endorsed through the International Association for Animal Hospice and Palliative Care (IAAHPC). You can find a published overview of this diagnostic quality of life scale for dogs on VCA Animal Hospitals and in the American Animal Hospital Association (AAHA) end-of-life guidelines.
Each letter in HHHHHMM stands for a category you score from 1 to 10. At the end, you add them up. The maximum score is 70. A score of roughly 35 or higher generally reflects an acceptable quality of life. Below that, most veterinarians who use a quality of life scale for dogs will begin a careful conversation with you about timing.
H — Hurt
Pain comes first because it has the biggest ethical weight on any quality of life scale for dogs. The question is not just, “Is my pet in pain right now?” It is, “Is my pet’s pain being managed well enough that they can rest?” That includes breathing labored, open-mouthed, or noisy breathing at rest is a form of distress even when the animal isn’t vocalizing.
Signs of inadequately controlled pain in pets include restlessness, panting when not hot, trembling, hunched posture, reluctance to move, sudden irritability, or a change in the way they hold their body. If your pet is on pain medication and still showing these signs, the plan isn’t working yet, and that is worth a call to your primary veterinarian.
H — Hunger
Is your pet able to eat enough to sustain themselves? Are they interested in food at all? On a clinical quality of life scale for dogs, appetite is a massive marker, then they refuse their treats, then they stop eating even hand-fed favorites. Some families score this category high because the pet “still eats,” but it is worth being specific about what eating looks like: is it normal, reduced, coaxed, or syringe-fed?
Nausea often hides in this category. A pet that approaches the bowl, sniffs, and walks away is often nauseated rather than simply “picky.” Your veterinarian can help identify whether anti-nausea medication might restore appetite and improve their ranking on the quality of life scale for dogs.
H — Hydration
Dehydration is one of the most uncomfortable states for a dying pet and also one of the most treatable during a hospice phase. A quick check for your quality of life scale for dogs baseline: gently pinch the skin between the shoulder blades. If it snaps back immediately, hydration is decent. If it stays tented, the pet is dehydrated. Gums should feel moist, not tacky or dry.
For pets not drinking enough, subcutaneous (under-the-skin) fluids given at home can meaningfully improve comfort. This is an area where a hospice vet can coach you to elevate your pet’s score on the quality of life scale for dogs.
H — Hygiene
Cats are especially distressed by soiled fur; dogs tend to be more stoic but dignity matters to both. Can your pet reach a pee pad or go outside in time? Are they lying in soiled bedding? Are they able to keep themselves clean, or are mats, urine scald, or pressure sores starting to appear?When these issues emerge, they reduce the scoring on the quality of life scale for dogs.
Hygiene also touches on pressure sores in very mobility-limited pets. Rotating them every few hours, using memory foam beds, and keeping skin dry can help. But if hygiene requires constant intervention and the pet is distressed by it, that score needs to drop honestly.
H — Happiness
Happiness is the hardest to score because it is the most subjective—and also one of the most important elements of a quality of life scale for dogs. Ask yourself: are there still moments when my pet seems genuinely present? A tail wag at a familiar voice, a purr, a lean into your hand, a gentle nudge for attention? Or is the face increasingly flat, the eyes distant, the response to the world muted?
A pet does not need to be bouncing and playing to score high here. The question is simpler: is there still pleasure? Is there still a connection? If those are gone, even a physically stable body is often giving a very clear answer.
M — Mobility
Mobility needs depend on the animal. A 14-year-old cat may move just fine if she can reach her water bowl and litter box in a small apartment. A large-breed dog may need to be able to rise without help and walk outside to relieve himself. The relevant question on a quality of life scale for dogs is: can your pet meet the basic needs of their life with or without your help?
If your dog cannot rise without being hoisted, if your cat has stopped using the litter box because she can’t climb into it, if walks are down to a few steps and then a collapse mobility is in trouble. Ramps, slings, non-slip rugs, raised bowls, and pain management all help during hospice. But when mobility is gone and the pet is distressed by it, the score should reflect that.
M — More Good Days Than Bad
This last category is the one I ask families to keep a rough journal on to accurately tally the quality of life scale for dogs. A simple check mark in a notebook on a good day, a bad day, or a mixed day is enough. You are not grading perfectly; you are noticing the trend.
When the bad days begin to outnumber the good, and the gap is widening week over week rather than recovering, the answer is usually becoming clear. Many families tell me, in retrospect, that they knew about two to three weeks before they were ready to admit it.
How to Use the Total Score
Score each of the seven categories from 1 (worst) to 10 (best) and add them together to calculate the quality of life scale for dogs:
- 56–70 Quality of life is strong; focus on preventing decline and treating pain early.
- 42–55 Decline is underway; hospice care and a plan with your veterinarian are appropriate.
- 35–41 Comfort is becoming fragile; begin conversations about timing and what a peaceful goodbye would look like on the quality of life scale for dogs.
- Below 35 Most hospice veterinarians would suggest that the pet’s day-to-day experience is becoming difficult enough that planning a peaceful transition is the kindest next step.
Score over days, not in a single moment. A pet on a good day in a warm patch of sunlight may score higher than the average week. What matters is the trend.
A Simple Way to Track It at Home
Take a sheet of paper and, every evening for a week, write the seven letters and a number beside each. Add the total. After seven days you will have a real picture and more importantly, you will be able to see the direction the score is heading.
Families sometimes resist this exercise because it feels clinical. But I have watched it help people more than almost anything else. The numbers do not replace love; they give love a way to look clearly.
Frequently Asked Questions
Is the quality of life scale just for dogs?
No. The HHHHHMM scale works for cats and dogs. Some categories (like mobility) look different in cats, a cat who can no longer jump into her favorite window or reach her litter box has a meaningful mobility problem.
What if my pet has a really good day after a bad week?
A good day is a gift, not a reason to delay a plan. The scale is about the trajectory over days and weeks, not a single good morning.
Can my primary vet help me use this scale?
Yes, and most will. You can also go through it with a hospice-trained veterinarian on a quality-of-life call. Sometimes a fresh set of eyes helps.
Does a score below 35 mean I have to euthanize immediately?
No. It means a conversation about timing is appropriate. Many families use a low score as the moment to begin planning, not panic.
If You’d Like to Walk Through the Scale Together
You are welcome to call me at 631-371-2919 or reach out through the contact page for a gentle phone conversation. I serve East Setauket, Stony Brook, Port Jefferson, Mount Sinai, Miller Place, Saint James, Smithtown, and the surrounding North Shore service area. We can go through each category together, no obligation, no urgency. Sometimes that is the most useful half hour a family spends in the whole process.
