Quality of life and saying goodbye: a compassionate, practical guide

There is no more difficult question in pet ownership than: "Is it time?" For many people, it is the first time they have faced an end-of-life decision for any being in their care. The fear of acting too soon is matched by the fear of allowing suffering to go on too long. The goal of this guide is to offer evidence-based, compassionate tools — developed by veterinary palliative-care specialists — to help navigate that question with clarity and care.

Veterinary palliative care and hospice medicine has developed significantly in the past two decades. Frameworks now exist to help owners and veterinarians assess quality of life in a structured way, plan for what is coming, and make decisions that honour the dog's dignity and the owner's values. You do not have to face this alone, and you do not have to figure it out from first principles.

Euthanasia — from the Greek for "good death" — is legal and widely available through veterinary practice. The AVMA considers it the humane, ethical choice when an animal's quality of life cannot be maintained at an acceptable level. The decision is ultimately the owner's, guided by the veterinarian, and it is an act of care — not abandonment.

Quality-of-life assessment frameworks

Several validated tools help quantify quality of life in a systematic, less emotionally subjective way. The most widely used in companion-animal medicine is the HHHHHMM Scale, developed by Dr. Alice Villalobos, a veterinary oncologist. It assesses seven domains, each scored 1–10.

• Hurt: Is pain well controlled? Can the dog breathe comfortably?
• Hunger: Is the dog eating enough? Can nutrition be maintained by hand-feeding or appetite stimulants?
• Hydration: Is the dog well hydrated? Assess skin turgor and mucous membranes
• Hygiene: Can the dog be kept clean and free of sores? Is the coat manageable?
• Happiness: Does the dog express interest, joy or respond to family and favourite things?
• Mobility: Can the dog move well enough, without assistance, to a degree that satisfies the dog?
• More good days than bad: Overall, is the animal experiencing more positive time than suffering?

A total score above 35 (out of 70) is considered acceptable quality of life. Below that threshold, euthanasia is worth a serious discussion with your vet. The scale is a guide, not a decree — but it provides a structured, repeatable way to track change over time and have a shared language with your veterinary team.

Signs that quality of life may be deteriorating

• Uncontrolled pain that no longer responds adequately to medication
• Inability to eat or drink, or aspiration risk with every attempt
• Severe, uncontrollable breathlessness
• More bad days than good — a persistent pattern, not an isolated difficult day
• Complete loss of interest in interaction, food or the environment
• Inability to perform basic functions (urinate, defecate, change position) without significant distress
• Advanced disease with no reasonable further treatment options and progressive suffering

What to expect from euthanasia

Veterinary euthanasia is a two-stage process. First, a sedative is administered — either by injection or as a pre-sedation medication — to relax the dog deeply. Then an overdose of a barbiturate (most commonly pentobarbital) is injected, causing cardiac and respiratory arrest within seconds. The dog is unconscious before the heart stops. It is typically peaceful, faster than owners expect, and far gentler than the images people fear.

You have the right to be present, and most owners who choose to be there feel it was the right decision. You also have the right to bring a person for support, to play music your dog loved, and to take as long as you need to say goodbye before and after. Clinics vary — call ahead and ask what the practice allows so you can prepare.

Aftercare: options for the body

• Individual cremation: the body is cremated separately and ashes returned to the owner — available through many veterinary practices via pet cremation services
• Communal cremation: cremated with other animals; ashes not returned
• Home burial: legal in some jurisdictions (check local regulations); requires sufficient depth to prevent disturbance
• Pet cemetery: formal burial in a licensed pet cemetery

Grief after pet loss: it is real

The grief of losing a dog is genuine, significant and sometimes misunderstood by people who have not experienced it. Research on human-animal bonds confirms that pet loss can cause grief as intense as the loss of a human relationship, particularly for people who live alone or for whom the dog was a primary companion. Grief typically includes disbelief, sadness, guilt (especially around euthanasia decisions), and physical manifestations such as sleep disruption and appetite changes.

There is no correct timetable. Seek support — from a friend, a pet-loss support group, or a mental-health professional with experience in grief. In Singapore, the SPCA and several veterinary clinics offer pet-loss support resources. In Australia, the RSPCA and university veterinary schools often provide referrals to pet-loss counsellors.
