How do you know when it's time to say goodbye to your dog?
It's usually time when bad days outnumber good ones, and pain, breathing trouble, not eating or not being able to get up can't be managed. Your vet can help you judge it, and you're not alone in facing it: 83.0%[1] of dog deaths in one large US study were by euthanasia.

What to watch
What are the signs a dog's quality of life is failing?
Most vets look at the same core questions. Is your dog in pain that medication no longer controls? Are they eating and drinking? Can they breathe comfortably at rest? Can they get up, move around and toilet without distress? Do they still greet you, enjoy a sniff or a treat, and seem like themselves?
- Pain: panting at rest, restlessness at night, crying out, reluctance to be touched.
- Appetite: refusing food for more than a day or two, or only eating by hand.
- Mobility: falling, being unable to rise, or needing to be carried outside.
- Breathing: labored breathing, coughing fits, gums that look pale or bluish.
- Hygiene: soiling themselves and lying in it.
- Joy: no interest in the things that used to light them up.
Many vets use a quality-of-life scale, such as the widely used "HHHHHMM" scale covering hurt, hunger, hydration, hygiene, happiness, mobility and more good days than bad. Scoring each day gives you something steadier than a feeling.
A simple method
How can you track good days and bad days?
Put a calendar on the fridge. Each evening, mark the day with a smile or a frown, or give it a score from 1 to 10. After two or three weeks a pattern appears that's hard to argue with, even on the days your heart wants to. Some families use two colored jars and drop in a bean each night.
Also write down your dog's three favorite things: maybe the morning walk, a certain toy, meeting you at the door. When they can no longer do two of the three, it's time to have a serious conversation with your vet.
Age matters too. According to US clinic life tables, US dogs live about 12.69 years[2] on average, and large breeds less. The pet age calculator shows roughly where your dog is in their senior years. By our calculation, small-breed dogs in the US outlive giant breeds by about four years[3], so a Great Dane's senior years start much sooner than a terrier's.
The hardest part
Is it better to say goodbye too early or too late?
There's a saying among vets: better a week too early than a day too late. It's meant kindly. A planned goodbye on a reasonably good day, calm, at home or in a quiet room, is gentler for your dog than a crisis at 3am.
Owners who feel part of the decision tend to cope better. A 2025 study of bereaved owners found grief was heavier when people felt excluded from the euthanasia decision by their vet, or regretted acting too soon[4]. Ask your vet to talk it through with you honestly, and ask what they'd do if it were their dog.
Cost is rarely the driver, and it shouldn't feel like it is: in the Dog Aging Project, no owner named cost as the main reason for euthanasia, and only 4.3%[5] gave it as a secondary reason.

Grieving early
Why does it hurt so much before your dog has even gone?
That's anticipatory grief, and it's very common: 75.4%[6] of owners in a large RSPCA survey felt it. You may cry at ordinary moments, feel guilty for enjoying a good day or find yourself watching your dog breathe at night. It isn't disloyal; it's love doing its work early.
Use this time well. Take photos and short videos, go to a favorite beach one more time, let them eat something forbidden. The private grief check-in can help you notice how you're coping, and our article on grief after losing a dog covers what comes after.

Making them count
How can you make your dog's last days good ones?
Think small and sensory. A slow sniff around the block matters more to an old dog than a long hike. Warm roast chicken, a sunny patch of floor, a car ride with the window down, their person lying on the floor beside them: these are the things dogs love most.
Ask your vet about comfort care in the meantime: stronger pain relief, anti-nausea medicine, appetite stimulants, non-slip rugs and a sling to help with stairs. None of it has to be about fighting the illness; it's about making the time easier. Many families also take a paw print or record their dog's snoring while there's no rush. Our memorial ideas for dogs include several keepsakes that are easiest to make now.
Getting ready
What should you plan once you've decided?
- Where. At home with a visiting vet, or at your clinic. In the Dog Aging Project, 60.1%[7] of euthanized dogs were put to sleep by their regular vet.
- When. A quiet time of day. Some clinics offer the last appointment of the day or a side door.
- Who. Family, children if they want to be there, other pets.
- Aftercare. Cremation or burial, private or communal. Decide now so nobody asks you afterwards.
- Keepsakes. Paw print, nose print, fur clipping, collar.
The farewell planner turns these choices into one page you can share. Our guide to saying goodbye at home explains costs and the handover to cremation, and the private vs communal guide helps with the aftercare choice.
Afterwards
Will you feel you got the timing right?
Almost everyone doubts themselves afterwards, whether they acted early or late. That doubt is a sign of how much you cared, not a sign you got it wrong. If you kept your dog comfortable, spared them a crisis and were with them at the end, you did right by them.
There's rarely a perfect day. There's a kind day, and you chose it.

Questions people ask
How do I know if my dog is suffering?
Signs include panting or restlessness at rest, hiding, crying out, reluctance to move or be touched, refusing food, labored breathing and changes in posture such as a hunched back. Dogs often hide pain, so small changes matter. Your vet can assess pain and tell you whether it can still be controlled.
Should I be with my dog during euthanasia?
It's your choice, and there's no wrong answer. Many owners find comfort in being there so their dog's last moments are with them, and vets generally encourage it. If you can't face it, you can say goodbye beforehand and ask a trusted person to stay.
Is it wrong to euthanize a dog who still eats?
No. Appetite is only one sign. A dog can still eat while struggling to breathe, being unable to stand or living with pain that can't be controlled. Look at the whole picture, including mobility, comfort and joy, and talk to your vet.
What does my vet mean by quality of life?
It's an overall judgment of whether your dog's days are more comfortable and enjoyable than not. Vets often assess pain, appetite, hydration, hygiene, happiness, mobility and the ratio of good days to bad. Many use a scoring scale you can fill in at home.
Can I schedule euthanasia in advance?
Yes. Many owners book a date a few days ahead so family can visit and the goodbye can be planned calmly. You can usually move the appointment if your dog rallies, or bring it forward if they decline. In-home vets in particular often need booking ahead.
