Companion Animal Grief: Supporting Pets Through Loss

Dogs, cats, and other companion animals grieve the loss of bonded companions; recognizing and supporting this process is an important aspect of multi-pet household welfare.

Key Facts

Studies document behavioral changes consistent with grief in dogs and cats following the death of a bonded companion
Grieving animals may show reduced appetite, increased vocalization, lethargy, and searching behavior
The grieving process in dogs and cats typically lasts weeks to months but can persist longer in some individuals
Maintaining routine — consistent feeding times, walks, and interaction — helps grieving animals adjust
Introducing a new pet too quickly after a loss can cause additional stress rather than alleviating grief
Veterinary attention is warranted if grieving animals show prolonged appetite loss or significant behavioral change

Welfare Considerations

Animal grief is a real phenomenon supported by behavioral and physiological evidence. Bonded companion animals experience measurable changes in behavior and stress physiology following the loss of a companion — whether human or animal. Owners who recognize and respond to grief in their pets — maintaining routine, offering extra attention, and monitoring health changes — support their animals through a genuine period of emotional difficulty. Veterinary guidance is valuable when grief manifests as prolonged illness or severe behavioral change.

What You Can Do

Maintain consistent daily routines for remaining pets following the loss of a companion animal
Watch for signs of prolonged grief — persistent appetite loss, lethargy, or behavioral change — and consult your vet
Allow sufficient time before introducing a new animal into the household after a loss
Consider pet loss support resources for yourself as well; your grief affects your ability to support your animals
