Do Pets Grieve? How Animals Experience and Are Affected by the Death of a Family Member

The short answer: Yes — animals do grieve. Dogs, cats, horses, and other companion animals show observable signs of grief when a family member (human or animal) dies. Supporting grieving pets requires maintaining routine, providing extra affection, and watching for prolonged behavioral changes. Meanwhile, pets often provide profound comfort to their human family members through bereavement.

Do Animals Really Grieve?

The scientific community has moved toward consensus: many animals, particularly social mammals, do experience something that functions like grief. Observed grief behaviors in companion animals include:

• Searching for the absent person or animal
• Loss of appetite or eating less
• Lethargy and sleep changes
• Vocalizing (whining, howling, meowing)
• Behavioral changes — becoming clingy or becoming withdrawn
• Spending time at the places the deceased person frequently occupied

Wild animals also show grief behaviors: elephants returning to the bones of deceased family members; orca pods staying near a dead calf; chimpanzees showing social withdrawal after group member deaths.

How Dogs Grieve

Dogs are particularly notable grief observers. Research and clinical observations show dogs often become visibly distressed when a primary human attachment figure dies or leaves. Common signs include:

• Waiting at the door or searching the house
• Reduced interest in play and walks
• Sleeping more or having disrupted sleep
• Eating less
• Seeking comfort from remaining family members
• In some cases, lying on the deceased person's belongings

How Cats Grieve

Cats are often wrongly considered emotionally unattached. When a bonded human or animal companion dies, cats may:

• Search for the absent family member
• Become unusually clingy or unusually distant
• Change their eating or sleeping habits
• Vocalize more
• Mark territory more as a stress response

Supporting a Grieving Pet

• Maintain routine: Consistent feeding and walk schedules provide comfort and security
• Extra attention: More play, affection, and quality time with remaining family members
• Allow them to be present: Some pet owners allow animals to smell the deceased person's clothing or belongings, which may help with processing
• New enrichment: New toys, activities, or play if the pet becomes excessively withdrawn
• Veterinary check-in: If a pet stops eating entirely for several days, veterinary consultation is appropriate
• Time: Pet grief typically resolves over weeks to months with extra care

The Gift Pets Offer Grieving Humans

While pets grieve too, they also provide extraordinary support to human family members in grief:

• Unconditional, non-verbal presence
• Physical warmth and touch that soothes the nervous system
• Routine and purpose that requires getting out of bed
• Moments of joy, play, and connection when other joy is absent
• A witness to the family's grief

Many grief counselors note that companion animals are among the most effective grief supports for humans — and caring for a grieving pet may help a grieving human feel useful and connected.

Frequently Asked Questions

Should I show my dog or cat the body of a deceased family member?

Some pet owners and animal behaviorists believe allowing pets to see and smell a deceased family member or animal companion may help them understand the absence and process the loss, potentially reducing prolonged searching behavior. There is no definitive research, but many owners report that it seemed to help their pet. If you choose to do this, allow the animal to approach at their own pace.

How long do pets grieve?

Pet grief duration varies by species and individual. Most pets show observable grief behaviors for days to weeks after a loss, with gradual return to normal behavior over 1-3 months. Some pets, particularly those who have lost a primary human attachment figure, may show prolonged behavioral changes. Maintaining routine and extra affection significantly helps.

Can pets develop depression after a death?

Yes — pets, particularly dogs and cats, can develop behavioral depression after a significant loss. Signs include persistent lethargy, complete appetite loss, withdrawal, and unresponsiveness to play or affection over multiple weeks. While not identical to human clinical depression, prolonged behavioral depression in pets warrants veterinary consultation, as it can have physical health consequences.

Do horses grieve the loss of herd members or human companions?

Yes. Horses are highly social animals that form strong bonds. They show clear grief behaviors when a herd companion dies — calling out, becoming agitated, pacing the area where the horse died. They also form bonds with human caregivers and can show distress when these relationships end. Providing increased human interaction, maintaining routine, and where possible allowing them to be near other horses helps grieving horses.

Can I adopt a new pet to help a grieving pet?

This is complex. Introducing a new pet too quickly can add stress rather than comfort for a grieving animal who is adjusting to loss. Most animal behaviorists recommend waiting at least 3-4 weeks and allowing the grieving pet's behavioral return to normal before introducing a new companion. Consulting with a veterinarian or animal behaviorist before adopting a 'companion pet' for a grieving animal is wise.
