Surviving companion animals often grieve following the loss of a bonded companion, requiring welfare-aware support from owners.
The grief responses of companion animals following the loss of bonded companions are behaviorally real and indicate subjective suffering. Owners who understand this can provide appropriate support rather than misinterpreting grief symptoms. Maintaining routines, providing extra social contact, and consulting a veterinarian if symptoms are severe are appropriate responses. Timing of a new companion animal introduction should be guided by the surviving animals welfare needs.
