There's no correct or incorrect way to feel sorrow, but there are gentler ways to deal with the hurt and carry your emotions in ways that enable you to mend.
Most of us share overwhelming love for our animals, so it’s normal to feel forsaken heartache and sorrow when a pet dies. While some people may not understand the depth of feeling you had for your pet, you should never feel guilty or ashamed about grieving for an animal friend. Instead, use these healthy ways to cope with the loss, comfort yourself and others, and begin the process of moving on.
For many people a pet is not “just a dog” or “just a cat.” Pets are beloved members of the family and, when they die, you feel a significant, even traumatic loss. The level of grief depends on factors such as your age and personality, the age of your pet, and the circumstances of their death. Generally, the more significant the loss, the more intense the grief you’ll feel.
Grief can be complicated by the role the animal played in your life. For example, if your pet was a working dog or a helper animal such as a guide dog, then you’ll not only be grieving the loss of a companion but also the loss of a coworker or the loss of your independence. If you cared for your pet through a protracted illness, you likely grew to love him even more. If you lived alone and the pet was your only companion, coming to terms with his loss can be even harder. If you were unable to afford expensive veterinary treatment to prolong the life of your pet, you may even feel a profound sense of guilt.
