Written in a simple, understanding tone, this condolence letter is aimed at a child who has lost a pet.
Dear {Recipient},
I heard about your {animal}, {Name}, and I wanted to write you a letter to let you know how sorry I am about {him/her}. I know you loved {Name} very much, but nothing could have prevented this.
Sometimes pets die, and even though it's sad, we can still be happy about the times we had with them. Remember when you and {Name} went out and {happy memory with pet}? When you feel sad about {Name}, remember that {he/she} had a very good life.
I'll see you very soon, and we can talk more about {Name} then. Maybe we can even look at pictures of you and {Name} and talk about all the happy times you had together.
Love,
{Sender}
