Short direct answer
Yes, dogs can and often do grieve when a companion dog dies. Surviving dogs commonly show reduced appetite, low energy, searching behavior, changes in sleep, and clinginess toward their owners for one to eight weeks after a loss. This isn’t grief in the exact human sense dogs don’t understand death the way we do but it’s a real reaction to a missing pack member, a disrupted routine, and the absence of a familiar scent. Most dogs recover gradually with patience, structure, and extra attention. A small number need veterinary support if symptoms don’t ease.
Introduction
If you’ve just lost a dog and you’re watching your surviving dog wander from room to room, sniffing at an empty bed or waiting by the door at the time their friend used to come in from a walk, you’re probably asking yourself the same question thousands of grieving pet owners search for every year: does my dog know what happened, and is he grieving too?
The honest answer is layered. Dogs don’t process mortality the way people do — there’s no evidence they understand that death is permanent. But they absolutely notice absence. They notice a missing bark at the door, a bowl that doesn’t get filled, a scent that fades from the couch cushion week by week. For a dog whose entire world revolves around routine, smell, and social bonds, that kind of disruption can look a lot like grief.
This guide walks through what’s actually happening in your dog’s mind and body after losing a companion, how to tell normal mourning apart from something that needs a vet’s attention, and what you can practically do — today and over the coming weeks — to help your dog through it.
Signs That Your Surviving Dog Is Grieving
Recognizing the signs of grief in dogs is crucial for providing timely support. When one dog dies, the other may exhibit a range of behaviors indicating they’re mourning. Common symptoms include lethargy, where your once-energetic pup seems uninterested in walks or play. They might sleep more than usual or hide away in quiet spots. Loss of appetite is another red flag – refusing meals or treats that they previously loved.
Behavioral changes can also involve searching for the deceased dog. Your pet might wander the house, whining or barking at doors, as if expecting their companion to return. Increased clinginess is frequent; they may follow you everywhere, seeking reassurance. On the flip side, some dogs become withdrawn, avoiding interaction altogether. Vocalizations like howling or whimpering can occur, especially at night.
Physical signs might mimic illness, such as digestive issues or changes in grooming habits. If your dog stops playing with toys or shows aggression toward other animals, it could be part of their grieving process. These symptoms align with what veterinarians and animal behaviorists observe in grieving pets. It’s essential to rule out medical problems first, as grief can sometimes overlap with health issues.
To illustrate, imagine a pair of sibling dogs who’ve spent their lives together. After one passes, the survivor might lie in their sibling’s favorite spot, sniffing around nostalgically. Such actions underscore the depth of canine bonds. If you’re noticing these in your pet, document them to discuss with a vet.

Scientific Evidence on Canine Grief
Is there solid science behind the idea that dogs grieve when another dog dies? Research and studies provide compelling evidence. A 2022 study published in Scientific Reports surveyed over 400 dog owners who had lost a pet in a multi-dog household. An astonishing 86% reported negative behavioral changes in the surviving dog, including increased attention-seeking, fearfulness, and reduced playfulness. These findings suggest that dogs do experience grief-like responses.
Animal psychologists like Dr. Marc Bekoff argue that dogs’ emotional intelligence allows them to mourn. Brain scans show similarities between human and canine emotional centers, indicating shared capacities for sadness. Anecdotal evidence from veterinarians supports this; many report dogs showing distress after a companion’s euthanasia.
However, skeptics point out that some behaviors might stem from routine disruptions rather than true grief. For instance, if the deceased dog was the “leader,” the survivor might act out due to role confusion. Yet, overall, the consensus leans toward dogs feeling genuine loss. Terms like “canine bereavement research” and “dog emotional studies” are gaining traction in veterinary science, pushing for more empathetic pet care.
In another study by the American Society for the Prevention of Cruelty to Animals (ASPCA), dogs in shelters exhibited mourning behaviors after separation from bonded pairs. This reinforces that social bonds are key to canine well-being. While more research is needed, current data affirms that when one dog dies, the other does grieve in meaningful ways.
How Long Does Grief Last in Dogs?
The duration of dog grief varies widely, depending on factors like the strength of the bond, the dog’s age, and personality. For some, symptoms might resolve in a few days or weeks, while others could take months. On average, noticeable changes last 2-6 months, but subtle effects can linger.
Younger dogs or those with resilient temperaments might bounce back quicker, whereas older dogs or those who’ve lost a lifelong companion may grieve longer. If grief persists beyond six months or intensifies, it could indicate complicated grief, warranting professional help.
Monitoring progress is key. Keep a journal of behaviors to track improvements. Remember, every dog is unique there’s no “normal” timeline for mourning pets.

Helping Your Dog Cope with the Loss of a Companion
Supporting a grieving dog requires patience and empathy. First, maintain routines to provide stability – stick to regular feeding, walking, and playtimes. Extra affection can help; spend quality time cuddling or engaging in gentle activities.
Allow your dog to process the loss. Some experts recommend letting them see and sniff the deceased body, as it may aid understanding. This “farewell” ritual can prevent prolonged searching behaviors.
Enrich their environment with toys, puzzles, or new scents to distract and stimulate. Exercise is vital; longer walks release endorphins, combating depression. If appetite wanes, try warming food or adding toppers.
Consider pheromone diffusers or calming supplements, but consult a vet first. Professional help, like from a certified animal behaviorist, can address severe cases. Avoid punishing grief-related behaviors; instead, redirect positively.
In cases of extreme distress, medications might be prescribed. Holistic approaches, such as acupuncture or massage, have shown promise in easing pet bereavement.
Should You Get a New Dog After One Dies?
Deciding to introduce a new dog during your pet’s mourning period is personal. While a new companion can provide distraction and companionship, rushing might overwhelm a grieving dog. Wait until symptoms subside, typically 1-3 months.
Choose a compatible breed and temperament. Introduce slowly, perhaps through playdates. Not all dogs need a replacement; some thrive as solo pets.
Pros include renewed energy and social stimulation. Cons: The new dog might not fill the void, leading to rejection. Weigh your dog’s signals carefully.
Real-Life Stories of Grieving Dogs
Pet owners worldwide share touching tales of canine mourning. One Reddit user described their dog becoming inconsolable after losing a sibling, pacing and whining for weeks. Another story from Quora highlights a dog refusing to eat until a new routine was established.
In a famous case, Hachiko, an Akita, waited daily for his deceased owner for years, epitomizing loyalty and grief. Modern examples include therapy dogs helping grieving pets in shelters.
These anecdotes humanize the topic, showing that dog grief is real and relatable.
