When a dog you love is getting older or living with a serious illness, one question starts to sit underneath every good day and every bad one: is my dog still comfortable? A dog quality of life scale won’t answer that for you, but it can help you look at the whole picture calmly, notice changes you might otherwise miss, and walk into your vet’s office with clear, specific observations.
Below you’ll find a free calculator based on the HHHHHMM scale used by many veterinarians, plus guidance on how to score each area honestly and what to do with the result. It works for cats too.
Quick Answer: How the Dog Quality of Life Scale Works
The HHHHHMM dog quality of life scale looks at seven areas of daily life, each scored from 0 to 10: Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility and More good days than bad, for a total out of 70. It was created by veterinary oncologist Dr. Alice Villalobos to help families and vets talk about comfort. On her guidance, totals above 35 are generally seen as compatible with good comfort care, while lower totals are a gentle sign that it may be time to talk with your vet about extra support.
Think about the last 24 hours and choose the number that feels closest, from 0 (very hard) to 10 (comfortable). There are no wrong answers. Your answers stay on this device.
Based on the HHHHHMM Quality of Life Scale created by Dr. Alice Villalobos, DVM. This is a tool to help you notice and talk about changes. It is not a diagnosis and it cannot make a decision for you. Your veterinarian is the best person to examine your pet and discuss options with you.
Where the HHHHHMM Scale Comes From
Dr. Alice Villalobos introduced the scale in 2004 to help families caring for pets with cancer, and later refined it for her work in pet hospice care, which she calls “Pawspice.” The name is a memory aid for its seven categories. Today it is widely shared by veterinary hospitals and appears in resources such as the Merck Veterinary Manual.
The scale was designed to be filled in by owners, not just clinicians, because you see your pet every hour of the day. That’s its strength: it turns a vague worry into seven concrete questions. Its limit is the same: the scores are your judgment, and two people in the same family may score the same day differently. That is normal, and it’s one reason to score regularly rather than once.
How to Score Each Area Honestly
Score each category based on the last 24 hours, not your pet’s best moment or worst moment. If you’re unsure between two numbers, choose the lower one and write down why. Here is what each area is really asking.
Hurt
Is pain well controlled, and is breathing easy? Pain in older dogs is often quiet: restlessness at night, panting at rest, reluctance to lie down, licking a joint, or a change in posture. Our guide to helping a senior dog with stiff legs covers the most common signs of joint pain. Pain is the area to take most seriously, because it is also often the most treatable.
Hunger
Is your dog eating enough on their own? Hand-feeding, warming food or offering favorites is fine to mention in your notes, but score what your dog actually eats. If appetite has dropped, read what to do when a senior dog stops eating and how long is too long to wait.
Hydration
Is your dog drinking enough, or needing fluids from the vet to stay hydrated? Dry gums, sunken eyes and skin that stays tented when gently pinched can all point to dehydration.
Hygiene
Can your dog be kept clean and comfortable? Think about the coat, accidents, and any pressure sores in dogs who lie down most of the day. A low score here is not a judgment on your care; it reflects how hard staying clean has become for your dog.
Happiness
Does your dog still greet you, respond to their name, enjoy food, toys or company? Signs of withdrawal, hiding or anxiety lower this score. Confusion and night-time pacing can also affect it; see our guide to signs of cognitive decline in senior dogs.
Mobility
Can your dog get up, walk, go outside to toilet and settle again without too much help? A dog who needs a sling or harness can still score in the middle if they are comfortable and willing; a dog who can’t rise at all scores low.
More Good Days Than Bad
Look back over the past week. Were there more days you’d call good than bad? This category matters most over time. Some families mark each day on a calendar with a simple happy or sad face, which makes the pattern hard to ignore.
What Your Dog Quality of Life Scale Score Means
- Higher totals: most parts of daily life still feel manageable for your dog. Keep doing what helps, and watch for any single area that starts to dip.
- Lower totals: daily life may be getting harder. This is a good time to talk with your vet about pain relief, appetite, rest and the support available. It is the start of a conversation, not a conclusion.
- One low area: even when the total looks reassuring, a low score for Hurt, Hunger or Hydration is worth mentioning to your vet, because these can change quickly and are often treatable.
The number is not a verdict. A dog recovering from surgery or a short illness can have a low score that improves, and a dog with a slowly progressing condition may stay comfortable for many months with good care. What tells you the most is the direction of travel, which is why the calculator gives you a personal summary each time and lets you keep a record over time.
How to Use the Scale Over Days and Weeks
- Pick a regular time. Score at the same time of day, for example in the evening, every two or three days, or daily during a difficult period.
- Let more than one person score. If partners or older children help care for your dog, compare scores. Big differences are worth talking about.
- Write down one sentence. A short note such as “wouldn’t climb the step to the garden” is often more useful to your vet than the number itself.
- Bring the printout. Use the free print button to take your scores and notes to your next appointment.
- Keep caring for comfort. Soft, supportive bedding, non-slip flooring, raised bowls and shorter, gentler walks can lift several categories at once. Our complete guide to caring for a senior dog has practical ideas.
When to See Your Vet
Do not wait for a low total if you notice any of the following. Contact your veterinarian promptly, or an emergency clinic out of hours:
- Labored, rapid or noisy breathing at rest
- Not eating for more than a day, or not drinking
- Collapse, sudden weakness or inability to stand
- Signs of severe pain: crying out, trembling, refusing to move
- Repeated vomiting or diarrhea, or blood in either
- Sudden confusion, seizures or loss of balance
If the scores keep falling, ask your vet about palliative care. Pain relief, appetite support, fluids and changes at home can make the remaining time more comfortable. Your vet can also talk you through what end-of-life care looks like, whenever you are ready for that conversation.

Frequently Asked Questions
Can I use this quality of life scale for my cat?
Yes. The HHHHHMM scale was created for pets in general, and the seven categories apply to cats as well as dogs. Switch the calculator to Cat and the questions adjust. Cats often hide pain and illness, so pay close attention to appetite, grooming and hiding behavior; our guide to a senior cat that isn’t eating explains why appetite changes in cats need prompt attention.
How often should I fill in the scale?
Every two to three days is a good rhythm for a stable older dog. During a flare-up or after a change in treatment, scoring daily for a week or two shows clearly whether things are improving. Try to score at the same time of day, because many senior dogs are stiffer in the morning and more settled in the evening.
What does a total around 35 mean?
It usually means your dog is managing in some areas and finding others harder. Rather than focusing on the number itself, look at which areas scored lowest: pain, appetite and hydration in particular are often things your vet can help with. Bringing your scores to an appointment is a good way to start that conversation.
Does a low score mean it’s time for euthanasia?
Not on its own. The scale was designed to support that conversation, not to make the decision. A low score tells you your dog is struggling right now. Your vet can tell you whether treatment or comfort care could improve things, and help you think through every option.
Is my information saved anywhere?
Your scores, notes and printable report stay in your own browser and are never sent to us. You do not need an email address to use any part of the calculator. If you separately choose to sign up for our occasional email guides, we store only your email address, never your pet’s scores, and you can unsubscribe at any time.
Final Thoughts
No scale can measure how much a dog means to you, and no number should make a decision for you. What a quality of life scale can do is help you notice, track and explain. It gives you something steady to hold onto on difficult days and something concrete to share with your vet. If your dog’s scores are dipping, start with comfort: our guide to why senior dogs sleep more and when it’s a concern is a good next read.
