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.

  3. Hi Melody, it's very painful to lose our pets; when my dear cat passed away, I felt lost. Thank you so much for your visit to my blog and for your comment, see you soon :)

  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.

  6. Hi Melody, oh the grief is real. I've always had a deep connection to all my fur babies. Losing them was one of the hardest things I've had to deal with. I still miss my very first cat.

  7. It's very true Melody. We in this house lost two dogs and my mother all in the one year - such a sad and grieving time for all of us.

  8. Me hiciste pensar en eso, porque para mi, analizando esos sentimientos...me sabe a tener un apego muy grande a una especie que te da confort personal...yo no tengo mascotas, no desarrolle ese apego permanente, aunque tuve si algun perruno que me acompaño en la niñez y adulto joven, pero se fueron y cuando se fueron siendo niña, comprendí que ellos no son eternos y que igual que nosotros se mueren y lo sentimos en su momento, pero después tenemos otros y así la vida sigue...como sea el amor dependiente que tienen algunos con sus mascotas se entiende , cada quien valora y por voluntad propia quiere depositar su querer ahi...y es de esperar que ese amor bien habido sirva para saber tener sanas relaciones con sus iguales, porque muchos aman a mascotas, pero andan de maltratadores con sus semejantes...el ser humano es muy increible en como se apondera de la vida y se justifica en sus acciones...

    Hay que aprender mejor de saber bien como amar y desapegarse en bien de todo ello.

    Te dejo un abrazo.

  9. If you really love your pet than I can understand this. As for me..I don´t have this experience because I do not have pets and never had...and I never will. That simply is not my thing.
    Have a good time and thanks for your always so kind visits to my blogs.

  10. Oi Melody, um texto muito importante sobre o sofrimento provocado pela perda de um animal de estimação. É realmente muito dolorido e demora a passar. Eu perdi uma gatinha há muitos anos, ela era minha companheira de vida. Fiquei arrasada, foi difícil demais de superar.
    Por isso que até hoje não consegui ter outra gatinha ou cãozinho: meu coração não suportaria outra perda.
    Beijos e uma ótima semana!!

  11. Yes, pets are members of our family. I had a German Shepherd who got sick and died at the age of 12, there's not a day that goes by that I don't think of him.

  12. I have a very large furry zoo and in recent years we have had at least one loss per year. Whoever tells me that it is not the same as losing a family member, I can assure you that it is not true; to me, they are like family, actually even closer. Then I always say that I will not take any more animals, but then there is always some needy animal and we cannot turn our backs, and we are adopted by a new animal. At the moment I say that when the current zoo is all in heaven I will not have any more animals, then we will see what happens in the future!

  13. An extremely hard situation, Melody. We have an already mature dog and we don't want to think about it.
    Have a nice day, my friend.

  14. I agree. When we lost our precious Little Bit in 2015 I cried and cried for weeks and weeks. They are family members.

    Have a blessed day and week. ♥

  15. Pets are so much part of the family and the bond between human and pet is strong, any loss is greatly felt.

    All the best Jan

  16. Research also indicates that interpersonal bonds are weakening, and that, generally speaking, we are drifting apart. Families are choosing not to have children or, for various reasons, are postponing parenthood until later. For many couples and single individuals, pets have become part of the family and faithful companions. That is why the loss is so painful. Personally, for a very long time, I could not bring myself to welcome a new animal friend into my life.
    Best regards.🤗🫶

  17. This is very true. As a retired Vet Tech I have seen the grief in people after the death of a pet. In my own family Mr. M. and I have had several pets that crossed the Rainbow bridge. After the last one we decided not to have pets again.

  18. Been there! I told many people that losing Olga was worse than losing my parents. For one thing, my parents were both very old and understood what was happening to them. But I felt like Olga, though also old (for a dog), was looking to me to make things better, and my inability to do so felt like a failure. Pets are so utterly dependent on us, and also focus all their attention on us, so it's not surprising that combination generates an intense feeling of loss when they do finally go.

  19. Cada persona creo que mostramos nuestros sentimientos de una manera ante la perdida de un familiar o amigo y la perdida de una mascota.
    Yo creo que cuando peor estuve fue cuando murió un amigo a los 20 años en accidente de trafico. Incluso peor que cuando murió mi padre que un cáncer de páncreas se lo llevo en un mes, creo que me afecto mas en la salud ya que tengo problemas de tiroides y de tener controlado a un descontrol total.
    Aunque en casa siempre hubo perros para el manejo del ganado no recuerdo de que se moriría alguno si que recuerdo de uno muy enfermo cuando era pequeño.

    Saludos.

  20. My sister-in-law called her kiddos out of school when their cat died. The school wasn't so understanding when she said the death was of a pet and not a relative.

  21. Melody, thank you for your text. Your words mean so much to me… Even though my beloved kitten disappeared in early April 2025, I want to believe that he's alive, healthy, not hungry, happy, and that he'll come back to her and my parents someday!
    Melody, I send you my regards and wish you a happy week!

  22. For most people losing a pet is the same as losing a family member and can cause a lot of heartache and tears

  24. 唔計那些沒良心的主人,寵物就如家人一樣,過世怎會不傷心.

  25. I agree with this reflection. A few months ago, our family pet, who had been with us for 14 years, died. We miss him and feel a void that cannot be filled. We have to process the grief and find acceptance. Pets can be like our little brothers, at least that's how we feel at home.
