Death of a Pet Can Cause Prolonged Grief Disorder

Anyone who’s experienced the death of a pet knows how painful it can be, and recent research from the UK has shown that it can even lead to prolonged grief disorder (PGD), a mental health disorder that an individual can be diagnosed with only after the death of a person.

What Is Prolonged Grief Disorder?


Prolonged grief disorder can follow the death of a loved one, and it can last months or years. People who have PGD may feel like a part of them has died, and they may have trouble completing daily tasks or experience difficulty socializing. Feelings of despair and longing are also associated with this disorder.


Researchers wanted to find out if the grief experienced after the loss of a human is similar to that felt after the loss of a pet, and if PGD can follow the death of a pet like it can the death of a person. So, they surveyed 975 adults in the U.K. in 2024, and asked the participants to respond to the International Grief Questionnaire—Clinical Version (IGQ-CC).  


Survey Results Show the Impact of Pet Loss


Of the people surveyed, 84% said they experienced at least one of any type of bereavement. Also, 32.6% of respondents said they experienced a pet’s death. And of those who had experienced the death of a pet and a person, 21% said the pet loss was most distressing.


Those who experienced the death of parents or children had PGD at significantly higher rates, but 7.5% of those who had lost a pet also met the diagnostic criteria for this disorder.


This survey shows that the grief caused by the loss of a pet can meet the criteria for PGD, even though this condition is only diagnosed after the death of a human. Many individuals who experienced the death of a pet met the symptom criteria for this disorder, and experts also found that the symptom structure wasn’t different when participants reported the loss of people or pets.


If you’ve ever moved through deep grief after the death of a pet, you aren’t alone. This study raises the question: should people who experience pet loss be considered when diagnosing PGD?
