The loss of a pet is a major life event. After the death of a pet, many owners experience what psychologists call “disenfranchised grief”, the pain of a loss that’s not openly acknowledged or socially supported. Subsequently, their grief can worsen into clinical depression and withdrawal. While the majority of us feel grief at the loss of our pet, what incorporates that loss into our lives and softens the sadness is the act of mourning. It is important to recognize that the feelings associated with the loss of a pet, such as sadness, disbelief, and anger are all normal. Bottling up your feelings can lead to deep resentment and is stressful on the body, which can make you more vulnerable to illness.
