Do Dogs and Cats Grieve? How to Support a Pet After Loss

By Dr Duncan Houston

After a companion dies, a dog may search the house while a cat becomes quieter or more demanding of attention. These changes can be upsetting to watch while you are grieving too.

They deserve care, but they should not automatically be attributed to grief if appetite, health or comfort is changing.

Quick Answer

Dogs and cats can show grief-like behavioural changes after losing a companion, although we cannot know whether their experience matches human grief. Keep routines predictable, offer gentle contact and monitor eating, toileting and activity. Food refusal, marked lethargy or other physical signs need veterinary assessment rather than a prolonged wait for adjustment.

What does the evidence show?

Owner surveys describe changes in play, sleep, appetite, fearfulness and attention seeking after a companion animal dies. A study of bereaved dogs and a study of cats after companion loss support taking these observations seriously.

These studies rely on caregiver reports. They cannot fully separate the animal's emotional response from altered routines, loss of social interaction or the owner's own grief. It is more accurate to describe grief-like behaviour than to claim certainty about the pet's inner experience.

What changes might occur?

Some animals search familiar sleeping places, vocalise more, withdraw or seek extra closeness. Others seem largely unchanged. The relationship between the animals matters, and a pet may respond differently after losing a close companion than after losing an animal they mostly avoided.

Dogs and cats both need individual support. Cats may benefit from secure hiding places and easy access to separate resources; dogs may need gradual adjustments to walks and time alone.

Which signs need a vet?

Pain, dental disease, kidney disease and other illness can resemble withdrawal. Cats that stop eating are at risk of serious complications; Cornell's appetite-loss guidance recommends assessment rather than assuming an emotional cause.

How to help at home

1. Keep feeding, walks, play and bedtime as predictable as practical.
2. Offer contact when sought, with space to retreat.
3. Provide familiar, easy activities such as sniffing, gentle play or simple food searches.
4. Record actual food intake, toilet habits and changes in sleep.
5. Introduce unavoidable routine changes gradually.
6. Seek veterinary behavioural help if distress persists or daily function deteriorates.

Familiar bedding can remain if it seems comforting, but there is no requirement to preserve every scent. Do not use essential oils, human sedatives or unreviewed calming supplements.

Should a surviving pet see the body?

There is no strong evidence that this reliably prevents grief-like behaviour or provides closure. It may be considered if circumstances are safe and your vet agrees, but it should never be forced. Avoid exposure if poisoning, infection or the condition of the body makes contact unsafe.

When is this an emergency?

Collapse, laboured breathing, severe weakness, repeated vomiting or inability to pass urine needs urgent care. These are not signs to watch at home simply because a companion recently died.

Common mistakes

• Waiting days for a cat to resume eating.
• Forcing affection or activity.
• Bringing home another animal immediately as a replacement.
• Assuming a pet that appears unaffected did not have a bond.

Frequently asked questions

How long does pet grief last?

There is no fixed timetable. Monitor function and seek help for worsening or sustained distress.

Should I get another companion?

Only when it suits the surviving pet and household. A new animal can add stress as well as companionship.

Can my own grief affect my pet?

Changes in interaction and routine can influence them. Predictability and support for yourself may help both of you.

Respond to the changes you can observe: comfort, appetite, routine and engagement. Give space for adjustment without overlooking illness.
