The potential negative effects of a grief reaction can be significant. For example, research shows that about 40% of bereaved people will suffer from some form of anxiety disorder in the first year after the death of a loved one, and there can be an up to 70% increase in death of the surviving spouse within the first six months after the death of his or her partner. For these reasons, questionnaires that assess how much stress a person is experiencing usually places the loss of a loved one at the top of the list of the most serious stresses to endure. When considering the death of a loved one, the effects of losing a pet should not be minimized. Pets are often considered another member of the family, and therefore their loss is grieved as well. Making the decision to euthanize (painlessly put to death) the family pet once a family works with their veterinarian to determine
that the pet is suffering as a result of their age, specific illness, and/or general declining health can add stress to the bereavement process by leaving family members feeling guilty initially, but if done properly, can help families understand that they spared their beloved pet unnecessary suffering.
In addition to grief as an initial reaction to loss, the process can be aggravated by events that remind the bereaved individual of their loved one or the circumstances surrounding their loss. Such events are often referred to as grief triggers. Father’s Day or the beginning of the school year may cause the parent who has lost a child (or a child who has lost a parent) to feel distraught. A shared song, television show, or activity can remind the widower of the wife he lost or the child of the grandparent who is no longer living. Watching another child play with a pet may reduce a child whose pet has died to tears.
