Why Pet Loss Can Trigger Grief as Intense as Human Loss

The bond between a human and a pet is deeply unique, often providing a level of unconditional support that is hard to find elsewhere. Recent study published in PLOS One on January 14, 2026, confirms that the emotional pain following the death of a pet can be just as severe as the grief felt after losing a human loved one.

A study of 975 adults in the United Kingdom explored the intensity of various types of bereavement. The results revealed that for 21% of participants who had lost both humans and pets, the death of their animal companion was the most distressing experience of their lives, even when compared to the loss of close friends or family members.

Furthermore, the study found that approximately 7.5% of grieving pet owners met the criteria for prolonged grief disorder, a condition where debilitating distress lasts for a year or longer. This rate is remarkably similar to the frequency of prolonged grief seen after the loss of a sibling or a partner.

It is essential to recognize that this type of loss can have tangible health consequences, including headaches, dizziness, and chronic fatigue. For those experiencing deep, lasting sorrow, seeking professional counseling is a necessary step in the healing process. Validating this grief is the first step toward recovery.

  1. In some ways the passing of my cat was harder than the deaths of my parents. I think it is because animals can’t say goodbye. They seem innocent.

    You have left some nice comments at mine, Thank you.

    1. I understand you. For some people, losing a pet is incredibly difficult, and the bond they have can run very deep, which is completely understandable.

      For me, I would definitely feel the loss of a human more, but I can still respect how meaningful that connection with a pet can be.

      I’m really sorry about your cat.

  2. Olá, tudo bem?
    Interessante esse assunto. Eu já perdi alguns cachorros, pois sempre tenho algum comigo, mas confesso que não fiquei de luto como se fosse alguém da família. Procuro manter uma certa distância emocional dos meus pets, pois não os considero no mesmo patamar que um filho, uma esposa, uma mãe. Mas tenho visto que hoje em dia muitas pessoas estão profundamente ligadas aos seus pets ao mesmo tempo em que se afastam das pessoas. Não sei até que ponto isso é saudável.

    Um abraço.

    1. I can never equate a dog to a human. I understand that pets are a part of people's lives, and I totally respect that. However, I am surprised at Anvilcloud's comment, but I understand that people feel things differently. A dog is not a child and can never replace a child. People can act as if they are, say it, or try to follow whatever they want, but a dog is not a child. To me, that is a delusion that needs mental assessment. Everything has its place, and when things start getting mixed up, people begin acting crazy.

  4. Pets are part of the family, and losing them is like losing a family member. And I don't see humans as any more or less valuable than our pets. Pets aren't people, but they are like children in many ways. They would never replace my child for example, but they are my babies and I enjoy my time with them a lot. Have you ever had a pet? Just curious since you write about the loss. Have a great rest of your day.

    1. Humans are inherently more valuable than pets. While pets can provide emotional support and a sense of companionship, they are fundamentally animals with their own distinct roles and capabilities. Unlike humans, pets cannot drive themselves to the hospital in an ambulance, perform surgery, or fight in wars. They also cannot cook for disabled individuals, highlighting the unique contributions and complexities of human life. While some may develop a strong emotional bond with their pets, treating them as children, it's crucial to acknowledge that they are not, and never can be, human, regardless of the training they receive.

      That being said, the loss of a beloved pet can be devastating. I grew up in a household with numerous dogs, at one point having up to six. Despite this, I never formed the deep connection that my brother and father shared with them. While they clearly loved and cared for the dogs, they never referred to them as children or equated them to humans. This experience has led me to believe that as humans, we need to establish clear boundaries between what we want things to be and what they realistically are. Maintaining a clear sense of reality is extremely important. Thank you for your contribution, Erika.

  5. Such a powerful and meaningful post. I really appreciate how you validate the depth of pet loss, because the bond we share with them is real, and the grief can be just as intense as losing a loved one. It’s comforting to see this kind of understanding and compassion expressed so openly.

    Kisses

    1. Hi Joanna, thanks so much for taking the time to read this post. I sincerely appreciate it. I do believe that losing a pet can be an intense experience, but I don't wholeheartedly equate it to losing a human loved one. I respect and validate the feelings of those who do feel that way, but personally, I don't share that exact sentiment. Losing a pet undoubtedly takes a significant emotional toll on a person. However, I maintain that the pain of losing a person is distinct. I've experienced the loss of my sister, and we also lost my dad's dog. I have never dwelled on the dog's passing; my sister is constantly on my mind. I wonder what life would be like right now. I have never cried or shed a tear for my dad's dog, even though it was with us for years. So, personally, they are not comparable. That being said, I absolutely agree that losing a pet can be devastating.
