Animals grieve the loss of bonded companions, and understanding grief responses in pets allows owners to provide appropriate support during bereavement to minimize prolonged suffering.
Animal grief is a genuine welfare concern that is frequently underappreciated by owners who may interpret reduced activity and appetite as temporary adjustment rather than a mourning process requiring support. Bonded animals — particularly dogs and horses — show behavioral and physiological indicators of distress following companion loss that parallel human grief responses. Providing predictable routine, increased human interaction, and patience during the grieving period supports recovery. Veterinary guidance on timing of new companion introductions is important — premature introduction can increase anxiety in grieving animals who are not ready for new social challenges.
