The death of a pet or an animal to which one has become emotionally bonded can be an intense loss, comparable with the death of a human loved one, or even greater depending on the individual. The death can be felt more intensely when the owner has made a decision to end the pet’s life through euthanasia. While there is strong evidence that animals can feel such loss for other animals, this article focuses on human feelings, when an animal is lost, dies or otherwise is departed.
Effect of animal loss on humans
There is no set amount of time for the grieving process to occur. However, mourning is much more intense for a pet upon whom the owner was emotionally dependent. Additionally, some pet owners may feel unable to express their grieving due to social mores surrounding pets. If the pet owner internalizes the grief, the suffering increases.
The stages of grief proposed by Elizabeth Kübler-Ross was designed in relation to human death, but can be adapted to describe the grief process for the death of a pet. Indeed, pet death includes several lessons: 1) the relationship rather than the object (the animal) is central to understand the loss; 2) the manner of death/loss will affect the grieving process; 3) the age and living situation of the bereaved will affect the grieving process.
University of Michigan did a study of grief over loss of a pet, the study included 174 adults who had lost their pets. Participants were administered a modified CENSHARE Pet Attachment Survey. Results indicate that initially 85.7% of owners experienced at least one symptom of grief, but the occurrence decreased to 35.1% at six months and to 22.4% at one year. Males and females reported different rates on six of 12 symptoms surveyed. The severity and length of symptoms is significantly correlated with the degree of attachment to the deceased pet. These findings indicate that pet loss can be a potential area of clinical concern, especially if the person's attachment to the pet was strong.
Coping with death
Though well-meaning phrases like "time heals all wounds" can simply upset the grieving pet owner, it is true that the one factor required for all coping strategies is time. Coping also involves understanding the emotions surrounding the loss of a pet, and then accepting the emotions to focus towards positive solutions.
Coping strategies may include:
- Going through the grieving process
- Strengthening positive memories
- Seeking support from resources, organizations and individuals
- Seeking solace from one's own spiritual beliefs
- Preparing for a pet's death in advance
Types of loss
- Pet is missing (considered an unresolved loss)
- Pet is lost through divorce/separation
- Pet is accidentally injured or killed
- Pet is willfully injured or killed
- Pet is stolen
- Pet dies naturally
- Pet is euthanized
- Pet becomes very ill
Getting a new animal
One caveat is to carefully consider timing bringing a new pet into the home. Additionally, it is recommended to consider where the bereaved is in the grieving process. Choose the new pet for its own unique qualities rather than trying to replace the former pet.
A recent trend has seen some pet owners getting clones made of their deceased pets. A new TLC show called I Cloned My Pet profiles some of these pet owners who want nothing more than the return of their original pets. For these pet owners nothing will do but the original, and people will pay up to $100,000 for a cloning. Some people shown on the show waited for over ten years for the return of their pet.
Pet illness and death is gradually becoming recognized as similar to other forms of sickness and death in the family. In the UK, a variety of companies provide paid leave for such eventualities, with employment tribunals backing this in some instances where employment terms did not specifically mention pet loss.
Recent studies by insurers suggest that up to one in four pet owners are sufficiently affected by pet loss or illness to take time off, but that many feel this will be treated lightly and hence simply state they were sick. According to Petplan, 35% of people admitted to taking time off work to either settle new pets into the home or care for sick pets, and half of those admitted taking a whole week off, and according to Direct Line one in four pet owners "said they have been too upset to go into the workplace when their four legged friend died" and "many of those who did go into work after the death of their pet said they were unproductive."  The latter survey also noted that pet owners in the UK take "around 8 days off" due to grief at the death of a pet, and that "seventy-nine percent of people responding to the survey admitted they did not think their boss would be sympathetic, and the only way they could get time off work was by... pretending to be ill."

Beliefs about non-human death
Some world religions have held that beloved pets will join their families in an afterlife. Animal worship was common in the ancient world, influencing the burial practices of animals. Animal mummification was practiced in Ancient Egypt, and gave special significance to cats in some areas. Egyptians believed that mummification was imperative in order to gain admittance to the afterlife, and therefore the belief was that the mummification of these pets would ensure the animals’ immortality.
Some Ancient Egyptian families believed that mummified pets would keep the deceased company in the afterlife. The most common Egyptian pets included cats, dogs, mongooses, monkeys, gazelles, and birds. Many Egyptians loved their pets, and the customary process of mourning the loss of a loved pet included crying and shaving one’s eyebrows. Ancient Egyptian pets were given names like we name our pets today, evidenced by over 70 names deciphered inscriptions identifying pet dog mummies.
In the absence of a common religious belief, many pet owners have embraced the concept of the Rainbow Bridge. The concept, the origin of which is not clearly known, speaks of a metaphorical or mythical place of reunion where pets that die live in a paradisical version of limbo, rejuvenated and free of pain and suffering, until their companion humans arrive upon their deaths. At this point, the pet(s) run to their companion humans, and they enter heaven together, never to be parted again.
In Mormonism, all organisms (as well as the entire planet Earth) are believed to have a spirit, but that beings without the gift of free agency (the ability to know and choose between right and wrong) are innocent and unblemished spirits who go straight to Heaven when they die. Animals will be resurrected.
Animal chaplains are becoming increasingly popular for helping the bereaved family members deal with the loss of their pet to provide memorial services, spiritual reassurance, and grief counseling.

- "A number of large businesses have begun to allow their employees 'peternity' leave, in order to look after sick pets or take them to the vets. London delivery company The Courier Service introduced a "peternity" policy last July that lets workers claim two days' paid annual leave. Denise Fresco, human resources manager, said: 'It is awarded in the same way people might need time off for a baby or to look after a child.' Meanwhile, the Bank of Scotland allow workers to take time off work for sick pets, so long as they organise cover. Royal Mail has also said that it will consider allowing 'compassionate leave' if a pet dies." workplacelaw.com Jan 2007
- "In September 2006, Royal Mail had to pay employee David Portman an undisclosed amount for firing him after he took a week off work following the death of his dog. The week's absence, the last in a series of absences, happened in 2004 and Portman was dismissed from his job as a result. Portman’s lawyer argued that many of the previous absences were a result of workplace injuries and that Royal Mail's own procedures say that time off following bereavement is not counted against an employee's sickness record. The tribunal ruled Portman had been off for legitimate reasons and that Royal Mail had failed to understand and apply its own policy." workplacelaw.com Jan 2007
