Instructions
Select a condolence card that is appropriate. If the pet owner lost a dog, fore example, look for a dog-related condolence card as opposed to another type of animal. You can opt to purchase a card that is blank on the inside or one that already has a message. Another option is to make the card yourself if you are handy with crafts.
Address the card to the pet owner, starting with "Dear" and the owner's name. If you are writing the card to a family, include everyone's name on the card.
Write that you are sorry about the loss of the pet. Since you do not know the name of the pet that passed away, stick with a generic phrase, such as "I am so sorry to hear about the loss of your beloved pet." If you know what the pet's gender was, continue with a sentence such as "She will truly be missed." Only use pronouns if you are certain that the pet was a male or female.
Give your support. Tell the addressee(s) that you are there for her if she needs anything, and that you hope she recovers from the loss soon. If you have had a pet die before, and you know how it feels, share your own feelings about it by saying, "I know how hard it is to lose a part of the family."
Do not suggest replacement pets in your card. The person who lost the pet will need time to grieve the loss, and condolence cards are not the appropriate medium for bringing up other animals.
Keep the card as personal as you can make it without having to mention the pet's name. If possible, share a fond memory you have of the pet.
Close the condolence card with your love and support.
How to Write a Condolence After Loss of a Pet If You Don't Know Pet's Name
For many pet owners, pets are a part of the family, and losing a pet can be just as tragic as losing a loved one. You can show your support to a grieving pet owner by writing a condolence letter. It is best, of course, to include the name of the pet in the card if you know it. However, if you do not know -- or cannot remember -- the pet's name, continue to write the card without it. It's the thought of the condolence that counts.
