How to assess your old dog's quality of life

If you are here because a stiff, sore, slowing dog has made you start asking a question you do not want to ask, here is the single most useful thing on this page: there is an established scale for it. Dr. Alice Villalobos, a veterinary oncologist, published the HHHHHMM quality-of-life scale in 2004, and it is widely reproduced in veterinary practice - including in the Merck Veterinary Manual. It gives you seven things to score out of ten, a total out of seventy, and a threshold to watch. It is not a verdict. It is a way of turning something you feel into something you can track week by week, and discuss with your vet using the same words they use.

We will say the obvious thing once and then get on with it: this decision is yours and your vet's, and nothing on a website can make it. What a website can do is give you the published tool, explain how to use it without fooling yourself, and be honest about the parts that are hard.

The HHHHHMM scale, as published

Seven categories, each scored 0 to 10, where 10 is ideal. The acronym is Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad.

The published guidance on reading it: a score over 5 is acceptable in each category, and when a category drops below 5, intervention is needed. If the total is above about 35 and pain is controlled, the scale treats quality of life as acceptable with good supportive care. Where a category is below 5 and every available intervention has been tried, that is the point at which the published guidance says euthanasia should be considered - and the scale exists explicitly as a decision-making aid for that conversation, not a substitute for it.

How to score it without fooling yourself

Score the week, not the moment

Dogs rally for company. A dog that has been flat all afternoon will lift its head and wag when you sit down to score it, and you will write a 7 where the honest answer is a 4. Score on the same day each week, and score what the week looked like.

Write it down

The number matters far less than the direction. A single total tells you almost nothing; six weekly totals tell you whether you are on a plateau or a slope, which is the actual question. A note on your phone is enough.

Get a second scorer

Have someone else in the household score independently, and compare. The person who does the lifting and the laundry tends to score lower than the person who sees the dog at weekends, and the gap between them is useful information rather than an argument.

Separate "can't" from "won't be allowed to"

Mobility is the category most often scored too low on this site's kind of dog, because the limitation is frequently the house rather than the dog. A dog that cannot cross a slick kitchen floor, cannot get up off a flat bed, and cannot get onto the sofa is scoring badly on mobility - and all three of those are fixable for the price of a runner, a bed and a ramp. Fix the house, then re-score. If the number moves, the problem was the house.

Fix what is fixable first - then re-score

This is the part of the question this site can genuinely help with, and the honest order is cheapest-first.

• Pain control. Your vet's department, and the first conversation.
• Footing. A continuous run of non-slip rugs on the route your dog actually walks. A dog that is frightened of its own hallway scores low on mobility and happiness both.
• Getting up. A supportive bed at a height a stiff dog can leave - beds for an arthritic dog.
• A hand up. A rear-support sling turns an impossible potty trip into a two-minute one, which is a hygiene and happiness score.
• Hygiene. Waterproof layers and washable pads keep a leaking dog clean and dry, which is the one category where neglect does physical harm - incontinence gear.
• Weight. Still the strongest lever, still free - keeping a senior dog lean.

The conversation to have early

Have it before you need it. Ask your vet, at an ordinary appointment, three questions: what would you expect to see as this progresses; what is left in the toolbox for pain; and what would make you say we were at the end. Those three answers, written down while nobody is in crisis, are worth more than any amount of reading at 2am. Our guide to taking an arthritic dog to the vet covers getting there comfortably, and the stages of mobility decline is the map of what tends to come next.

What this page is not

It is not a verdict, it is not veterinary advice, and it is not a scale we invented - we have reproduced a published one and told you where it comes from. We have no basis for telling you what your dog's score means for your dog, and we would distrust any site that claimed otherwise. The scale's own framing is that it is a tool to help with a difficult process. Use it with your vet.
