Saying goodbye to a beloved dog is one of the hardest events in life. “With the decision to bring a puppy into your home, you are already buying into its death,” it is said. Yet we ignore this fact until the dog becomes noticeably frail. Knowing the signs of the dying process and how the stages of dying in dogs unfold allows you to care for your dog and yourself as best as possible.
What Are the Most Common Causes of Death in Dogs?
Talking to dog owners who have witnessed their dog’s natural death reveals that dying is a very individual process and depends on the specific illness. Some dogs die quite suddenly.
The causes of death are often heart diseases, such as atrial fibrillation and sudden cardiac death. However, it is hardly possible to predict how much time remains when heart problems are present. Many dogs are so well managed with heart medications that they can live well for many years, and other illnesses eventually lead to euthanasia.
In addition to heart diseases and cancer, kidney diseases are among the most common causes of death in dogs. One owner reports: “My male dog had Cushing’s syndrome (a hormonal disorder caused by an excess of cortisol, editor’s note). He died of multiple organ failure. Before that, he ate poorly for three days and then fell into a coma.”1
Typical Signs of Suffering and Farewell
Similar to humans, the dying process in many dogs begins with convulsions, shortness of breath, or howling. Others die in their sleep. Author and veterinarian Frigga Wiese defines suffering in dogs as a state in which the animal experiences physical and emotional pain, discomfort, or stress that limits its quality of life. “A dog’s suffering is not always shown by loud howling but often very quietly—through a vacant look or retreating to quiet places,” Wiese emphasizes.
What Are the Stages of Dying in Dogs?
When a dog dies, its body follows a natural process that usually occurs in several phases—a quiet transition that can provide owners with guidance and understanding. The dying process often follows similar stages:
1. Preparation Phase
- Retreating to quiet places
- More sleep, less response to environmental stimuli
- Decreased appetite, often refusal of food and water
2. Active Dying Phase
- Restlessness or a sudden urge to move, despite having little strength
- Irregular or altered breathing
- Twitching, trembling, or short episodes of convulsions
3. Peaceful End Phase
- The dog appears calm and relaxed, often lying motionless
- Partial loss of control over bladder and bowels
- Breathing becomes increasingly shallow
- Possible reflex actions, like a final sound or uncontrolled bowel movement
- The transition is often gentle and quiet
How to Recognize When the Farewell Is Near
Besides retreating, physical symptoms are crucial. However, these are not the same for all dogs:
- Pain, accompanied by vocalizations, panting, trembling, or convulsions
- Restlessness
- Refusal of food and water
- Changed body posture when lying down
- Incontinence and loss of control over their own body
Many dogs seek a lot of sleep and rest in the last days and weeks of their lives. They are less aware of their surroundings, and their bodily functions increasingly decline.2
How to Support Your Dog
When a dog is nearing the end of its life, owners can do much to ensure it still feels secure. Medical and practical support is just as important as emotional closeness. An individually tailored pain management plan, medications for nausea, or calming agents can significantly improve well-being and alleviate symptoms.
Small adjustments in daily life also help: These include easily accessible, non-slip food bowls, short paths to water sources, and non-slip floors so favorite spots remain reachable. A warm, soft, and regularly cleaned resting area is especially important—many old or seriously ill dogs lie down a lot and therefore need extra comfort and hygiene. Small, frequent meals and a constant supply of fresh water make it easier for the dog to be nourished, while gentle cleaning of the coat, paws, and eye area ensures cleanliness when it can no longer manage on its own.
Emotional Support
In addition to these practical measures, emotional support plays a significant role. A calm environment with clear structures and retreat options provides security. Gentle touches, a familiar voice, and accustomed rituals can have a calming effect. It is also important for owners to respect what the dog needs at the moment–whether it seeks closeness or prefers to be undisturbed. And finally, no one has to walk this last path alone. Support from family, friends, veterinarians, or counseling centers can relieve stress and help find strength for this special time.

When Is the Right Time for Euthanasia?
The animal’s well-being is paramount: “Beginning suffering, fear, chronic pain, or constant shortness of breath are boundaries that must not be crossed,” explains veterinarian Frigga Wiese in her work “My Pet Is Seriously Ill. What Now?”
If pain relief is no longer possible, it is the owner’s responsibility, according to animal welfare law, to decide on a dignified farewell together with the veterinarian.
What Really Matters in the End
Accompanying a dog through death requires a lot of sensitivity—but also clarity regarding possible suffering. Every dog and situation is individual. It is important to recognize when the quality of life of your own dog declines and a life appropriate to the species is no longer possible. A dignified farewell is a final act of love for the best friend, whether through natural death or euthanasia.
