While you are grieving, there is often another member of the household grieving too, one who cannot ask questions, cannot be told what happened, and can only respond to the sudden, unexplained absence of a companion they may have lived alongside for years. Surviving pets frequently show real, observable signs of grief after losing a companion animal, and supporting them through this is both a genuine welfare consideration and, for many owners, a meaningful part of processing their own loss.
Do animals actually grieve?
The evidence, both from behavioural research and from the consistent, detailed reports of owners across species, strongly suggests yes, at least in a meaningful behavioural sense. Surviving pets commonly show changes in appetite, sleep, activity level, and social behaviour following the loss of a bonded companion, particularly when the animals shared a long-term, closely bonded relationship. Whether this constitutes grief in the full human psychological sense remains a genuine scientific question, but the practical behavioural impact is well documented and worth taking seriously regardless of how it is ultimately classified.

Recognising grief in a surviving pet
Common signs include:
- Searching behaviour: looking for the companion in their usual spots, waiting by doors or windows, or vocalising in ways that suggest searching
- Reduced appetite or interest in food, sometimes significant enough to require veterinary attention
- Changes in sleep patterns, either increased lethargy or restlessness
- Increased clinginess toward you, or conversely, withdrawal and reduced interaction
- In multi-pet households, changes in social dynamics with any remaining animals, sometimes increased anxiety, sometimes surprising new bonds forming
Not every surviving pet shows obvious signs, and the absence of visible grief does not necessarily mean no impact at all, particularly in less demonstrative animals or species.
What can help a grieving pet
Maintaining as much routine as possible, feeding times, walks, general daily structure, provides a sense of stability during a period of real disruption to their environment. Some owners find it helpful to allow a surviving pet brief access to the deceased companion's scent, a bed or blanket, before it is washed or removed, which may help provide some behavioural closure, though this varies by animal and is not universally recommended by all behaviourists.
Extra affection and attention, without forcing interaction a withdrawn pet doesn't want, tends to help most animals through this adjustment period. If appetite loss or behavioural changes are significant or persist beyond a couple of weeks, a veterinary check is worth pursuing both to rule out unrelated health issues and to discuss whether the changes reflect a normal adjustment or something requiring more active management.
When to consider a new companion
There is no fixed rule about whether or when to introduce a new animal after a loss. Some surviving pets adjust well to a new companion relatively soon; others benefit from a longer period without one, particularly older or more routine-dependent animals who may find a new introduction stressful during an already unsettled time. This decision should be based on your individual surviving pet's temperament and apparent needs, not a general timeline or your own readiness alone.
Carrying the loss forward, together
Watching a surviving pet navigate their own version of this loss can be, for many owners, both painful and a strange source of shared understanding, a reminder that the bond you are grieving was real and mattered to more than just you.
trace.memorial exists to hold the story of the pet you lost, including, if you choose, the way their surviving companion responded and adjusted, as part of the fuller picture of the bond that existed in your household.
If you are navigating this alongside your own grief, a certified pet bereavement counsellor trained in the TRACE method can help you support both your own processing and your surviving pet's adjustment. Building a memorial yourself, whenever you are ready, is equally valid.
Frequently asked questions
Do dogs and cats really grieve the loss of another pet? Behavioural evidence strongly suggests many pets show real, observable responses to the loss of a bonded companion, including changes in appetite, sleep, and social behaviour, even if the full psychological experience is difficult to measure scientifically.
My surviving pet isn't eating well since our other pet died. Should I be worried? A short-term reduction in appetite is common, but if it persists beyond a few days or becomes severe, a veterinary check is worth pursuing to rule out other causes and discuss supportive options.
Should I let my surviving pet see or smell their companion's body or belongings? Some behaviourists suggest this may help provide behavioural closure for the surviving animal, though evidence is mixed and this is not a universal recommendation. It is a reasonable option to consider if it feels right for your situation.
How long does pet grief typically last in a surviving animal? This varies considerably, but noticeable behavioural changes commonly ease within a few weeks to a couple of months. Persistent, significant changes beyond this warrant a veterinary or behavioural consultation.
Should I get a new pet quickly to help my surviving pet adjust? There is no universal answer. Some surviving pets adjust well to a new companion relatively soon; others need more time. This decision should be based on your specific pet's temperament and apparent needs rather than a fixed timeline.
Is it normal to find some comfort in watching my surviving pet grieve too? Yes, many owners describe this as a strange but real source of shared understanding, a confirmation that the bond they are grieving was significant to the whole household, not only to themselves.
