When to Put Your Dog Down Checklist

The Decision Nobody Wants to Make

The hardest part of this decision isn't the answer — it's the uncertainty. You know your dog is declining. You can see it. But "declining" covers a range from "slower on walks" to "can't stand up," and the line between manageable discomfort and genuine suffering is not always obvious from the outside.

What helps is structure. Not a formula that spits out an answer, but a framework that forces you to observe systematically instead of swinging between hope and dread.

The Quality of Life Checklist

Rate each of these seven areas on a scale of 0 to 10, where 0 means the worst possible state and 10 means completely normal. This is based on the HHHHHMM scale developed by veterinary oncologist Dr. Alice Villalobos, adapted for home use. (For more detail on how each factor works, see our quality of life scale guide.)

1. Hurt (0–10) Is your dog in pain? Can the pain be managed with current medication? A low score or pain that remains despite medication is a reason to ask your veterinarian about pain control.

2. Hunger (0–10) Is your dog eating? Hand-feeding counts, but only if the dog is actually swallowing and keeping food down. A dog that turns away from favorite treats is scoring low here.

3. Hydration (0–10) Is your dog drinking water? Signs of dehydration include tacky gums, sunken eyes, and skin that doesn't snap back when gently pinched. Subcutaneous fluid administration at home can support hydration, but it's a management tool, not a fix.

4. Hygiene (0–10) Can your dog be kept clean and comfortable? Incontinence, pressure sores, and inability to groom are hygiene failures that affect dignity and physical health. A dog lying in its own waste despite your best efforts to keep them clean is suffering.

5. Happiness (0–10) Does your dog still respond to family members? Show interest in surroundings? Wag its tail, even weakly? Persistent withdrawal from interaction is a change to discuss with your veterinarian.

6. Mobility (0–10) Can your dog get up, walk, and reposition itself? Stumbling is different from paralysis. Needing help on stairs is different from being unable to stand. Mobility aids like slings and carts count if the dog tolerates them.

7. More Good Days Than Bad (0–10) This is the aggregate question. Looking at the past week, were there more days where your dog seemed comfortable, interested, and relatively pain-free than days where they were distressed?

Interpreting the total: The total can help show a trend, but it does not determine when euthanasia is right. Share the scores with your veterinarian and interpret them in light of your dog's diagnosis.

Physical Signs That the Body Is Failing

Beyond the quality of life scale, certain physical changes indicate that the body's systems are shutting down:

• Refusing all food and water for 24+ hours in a dog that was previously eating with encouragement
• Labored breathing — open-mouth breathing at rest, abdominal heaving, or gasping
• Inability to stand even with assistance, or collapsing after a few steps
• Uncontrolled vomiting or diarrhea that doesn't respond to medication
• Seizure clusters — multiple seizures in a 24-hour period
• Crying or vocalizing when touched or repositioned, despite pain medication

Any one of these warrants a prompt call to your veterinarian, who can assess what it means for your dog.

The "Too Early vs. Too Late" Trap

Owners can worry about acting too soon or waiting too long. The evidence and a dog's progression can be difficult to assess alone.

Your veterinarian can help interpret your dog's condition and discuss whether quality of life has declined to a point where euthanasia may be appropriate. If possible, ask in advance which signs of decline should prompt that conversation; planning can help avoid making the decision for the first time during a crisis.

How to Use This Checklist

Score your dog once a day, at roughly the same time. Write the numbers down — memory is unreliable when you're emotionally exhausted. After a week, the trend can add context to isolated daily observations.

Share the scores with your veterinarian. They can interpret the numbers in the context of your dog's specific diagnosis and give you a realistic picture of what the trajectory looks like from here.

If the scores are dropping and the trend is clear, start planning. Choose your in-home euthanasia provider. Decide who will be present. Think about aftercare — cremation costs, burial options, or memorial keepsakes.
