Pet Loss and Prolonged Grief Disorder Explained

Losing a pet can be devastating. Learn how Prolonged Grief Disorder (PGD) after pet loss differs from depression, PTSD, and anxiety—and when it may be time to seek help. 

When a beloved pet passes away, grief is inevitable. For many, the pain softens with time, even though the love and memories remain. But for some, the grief feels unending, like a wound that refuses to heal. This may be a sign of Prolonged Grief Disorder (PGD)—a condition that’s different from depression, PTSD, or anxiety, yet just as serious in its impact.

What Makes Prolonged Grief Disorder Different? 

PGD is a specific and intense reaction to the loss of someone (or a cherished animal) with whom you shared a deep emotional bond. While grief after pet loss is natural, Prolonged Grief Disorder often includes:

  • Persistent yearning or longing for your pet

  • Emotional numbness or detachment 

  • A loss of meaning or purpose in life

  • Feeling stuck in grief and unable to move forward 

Prolonged Grief Disorder vs. Depression 

Both PGD and depression can involve deep sadness, but they are not the same:

  • Depression can arise from many causes, not just loss. 

  • In depression, sadness tends to be more constant and generalized. In PGD, intense pain is usually triggered by reminders of your pet and the relationship you shared. 

  • PGD centers on the bond with the deceased companion animal, whereas depression is not relationship-specific. 

Prolonged Grief Disorder vs. PTSD 

PTSD and PGD can sometimes overlap, especially if your pet’s death was traumatic, but they have distinct features:

  • PTSD follows a trauma involving threat, danger, or intense fear; it doesn’t always involve bereavement.

  • PGD is focused on separation distress—missing and longing for the loved one who died. 

  • PTSD often includes unwanted intrusive memories and hypervigilance. In PGD, reminiscing is often deliberate; you may seek out memories of your pet, even if they bring pain. 

Prolonged Grief Disorder vs. Anxiety Disorders 

Anxiety disorders and PGD can both cause restlessness and worry, but they show up differently:

  • Generalized Anxiety Disorder (GAD) involves chronic worry about many areas of life. 

  • In PGD, distress is centered on missing one specific loved one, such as a pet.

  • PGD is driven more by longing and separation pain than by fear about the future.
