Dogs and cats show behavioral changes consistent with grief when a bonded companion dies. Understanding animal grief helps owners provide appropriate support during bereavement.
Animal grief is real and has welfare consequences that owners and veterinarians should take seriously. Bereaved dogs and cats experience genuine behavioral disruption that can include reduced food intake, disturbed sleep, loss of interest in play, and seeking behavior that indicates distress. These welfare impacts typically resolve within weeks to months but can be severe in animals with very close bonds. Owner responses matter: maintaining routine, providing gentle extra attention without forcing interaction, and allowing the bereaved animal to process the loss at their own pace are all supportive. Rushing to replace a deceased companion before the surviving animal has adjusted typically causes additional social stress. Veterinary attention is appropriate if grief-like behavior is severe or prolonged.
