Your old dog skipped breakfast again, and last night it took two tries to get up off the kitchen floor. Now you're wondering whether this is the beginning of the end, and whether you would even know if it were.
There is rarely one clear moment. Veterinarians look at a handful of everyday things, like pain, appetite, mobility, cleanliness, and joy, and whether the bad days have started to outnumber the good ones. If these changes are new, start with a vet visit, where your vet can assess your dog's condition and estimate the chances of recovery. Pain, appetite loss, and trouble standing sometimes have causes that can be treated. Then watching those things over a week or two, alongside your vet, usually tells you more than any single day can.
This article is not medical advice. Your veterinarian is the one who can examine your dog and assess their comfort and condition. If your dog is struggling to breathe, has collapsed, or seems to be in severe pain, call your vet or an emergency clinic now.
The questions vets often start with
The American Veterinary Medical Association's guide for pet owners offers a short set of questions that can aid your decision-making process:
- Is my dog suffering?
- Does my dog have more bad days than good days?
- Do they still enjoy the things they usually do and seem interested in what's around them, or do they seem consistently depressed and unresponsive?
- What are the chances they will recover from their condition?
- Will they need special care that I can't provide or afford?
That last question can feel uncomfortable. The AVMA includes it anyway and suggests thinking about what's best for your family, too, not only your dog.
The HHHHHMM quality of life scale, in plain words
One well-known tool comes from veterinary oncologist Dr. Alice Villalobos. She called it the HHHHHMM Scale, described in a 2004 Veterinary Practice News column and later in her 2006 textbook on geriatric oncology. Each letter stands for one area of a pet's life. In our own words:
- Hurt. Is pain under control, and can your dog breathe comfortably? Dr. Villalobos puts this first on the scale.
- Hunger. Is your dog eating enough, and does hand-feeding help?
- Hydration. Are they drinking enough to stay hydrated?
- Hygiene. Can they stay clean, especially after going to the bathroom? Are there sores from lying in one spot?
- Happiness. Do they still show interest in family, toys, and the world around them, or do they seem anxious, withdrawn, or afraid?
- Mobility. Can they get up and move around without help? Do they still want to go for a walk?
- More good days than bad. When the bad days outnumber the good, the scale notes that quality of life might be compromised.
In the original, each area gets a score, and your vet can walk you through it. Lap of Love, a national network of veterinarians focused on end-of-life care, offers its own free quality of life scale that you can print, and the Ohio State University Veterinary Medical Center includes a worksheet adapted with permission from the HHHHHMM scale in its guide for owners.
The guide adds two cautions. Every dog is an individual, so lying around all day may be a problem for one dog and normal for another. And some signs, like unrelenting pain or extreme difficulty breathing, should weigh heavily on their own, even if everything else looks okay.
A simple senior dog quality of life checklist
If a scored worksheet feels like too much right now, start with a few plain questions. Jot down one short note each evening, then go through all of them for a fuller check every few days or once a week.
- Did my dog seem to be in pain today? (Panting while resting, trembling, restlessness, or trouble settling down can be signs. Lap of Love lists these among the things to watch for.)
- Did they eat a normal meal, or only treats?
- Did they drink water like usual?
- Could they get up, walk, and go outside to potty without much help?
- Did they stay clean, or did they have an accident they couldn't move away from?
- Did they greet me, follow me, or show interest in anything they love?
- Overall, was today a good day, an in-between day, or a bad day?
Keeping a good-day, bad-day calendar
When a dog declines slowly, it's hard to see the change from the inside. A calendar helps. Ohio State's guide suggests marking good and bad days on a calendar, even with just a happy or sad face. As the bad days start to outnumber the good, it may be time to talk with your vet about euthanasia. Lap of Love describes the same turning point as bad days that keep outnumbering the good, even with medication and supportive care.
A few more ideas from the same guide:
- Write down three to five things your dog loves. A walk to the corner, a favorite toy, dinner, greeting you at the door. When your dog is consistently unable to enjoy these things, that is worth bringing up with your vet.
- Look at older photos and videos. Remembering how your dog moved and played before can make a gradual change easier to see.
- Pick a set schedule. Keep the evening note short, and do the fuller check with the checklist or scale every three days, or every Tuesday, so you're comparing like with like.
- Let each family member fill one out on their own. Then compare. People who spend time with your dog in different ways notice different things.
Lap of Love suggests tracking for about a month, or 7 to 14 days when things are more serious. Their quality of life article recommends looking for weekly patterns rather than a single day. One rough morning doesn't decide anything.
Talking with your veterinarian
Your vet can't make this decision for you, but they can give you an honest medical picture. According to the AVMA, your veterinarian can evaluate your dog's condition, estimate the chances of recovery, and explain treatment options, their costs, and likely outcomes. Bring your calendar or notes to the visit.
Ohio State's guide suggests a few questions you can ask:
- What are the best-case and worst-case scenarios for the options we have?
- How much pain or suffering do you think my dog is experiencing?
- Can you estimate how much time my dog has?
The AVMA also notes that some owners find it helps to talk with their vet ahead of time about which signs of declining quality of life will tell them that euthanasia may be the best option. Agreeing on those signs while things are calm can give you guardrails later, so you aren't deciding everything in a hard moment. It also says that while some decisions have to be made right away, you usually will have some time to talk it over with family and friends first.
Ask about in-home euthanasia
The 2016 AAHA/IAAHPC End-of-Life Care Guidelines, written for veterinary teams, say euthanasia can be performed in your home, something many pet owners prefer. The guidelines explain that it spares your dog the car ride, lets them stay somewhere familiar, gives you more privacy, and allows more family members to be there. The Ohio State guide adds that at-home euthanasia is offered by many veterinarians.
If this matters to you, ask your vet whether they offer home visits or can refer you to someone who does. It's a fine question to ask early.
Preparing your family and kids
Your family may already sense that something is changing. The AVMA suggests sharing what you've learned from your vet, encouraging everyone to say what they think and feel, and making sure family members, especially children, feel heard, even if you've already made a decision.
Before the day comes, it can help to decide together how you'll say goodbye. The AVMA mentions that a last evening at home or a visit at the hospital may suit different families, and that some people choose to be present while others say goodbye beforehand. Both choices are okay.

There is rarely one perfect moment
Many people hope their dog will "tell them" when it's time. Sometimes that happens. But Ohio State's guide says it plainly: often the choice is not clear. Many of these decisions come after a slow decline, and it can be hard to trust, day by day, that now is the moment.
The same guide also says that second-guessing is normal and natural, and that it does not mean you made the wrong choice. In cases of illness or declining quality of life, it says, there is truly no wrong decision, only the one you feel is best for your dog and your family.
What usually helps most is a pattern you can see on paper, an honest talk with your vet, and a decision you can live with.
Caring for yourself while you wait
Grief can start before your dog is gone. Ohio State's guide calls this anticipatory grief and describes it as very natural. It can bring sadness, denial, and trouble taking in information, so it helps to write things down and bring someone along to vet visits.
If the weight of this starts to feel like more than you can carry, you can call or text 988 at any hour. It's free and confidential, and you don't have to be suicidal to call.
Your dog doesn't need you to have every answer. They need you close, paying attention, and asking good questions. You're already doing that.
If this helped, you can pass it on to someone who is grieving.
If you are thinking about harming yourself, call or text 988 in the US, any time.
