The jobs animals do are many: they detect human cancers, rescue lost people, sniff out drugs and bombs, predict earthquakes and find termites, just to name a few. Besides being loyal companions, they help by guarding people and property.

We'd like you to be a part of the PetPlace tribute to working animals on the eve of this Labor Day. Email us with your story of an animal who is working to help others. If you have a picture, attach it as well. Be sure to include your name, address and phone number in the email in case we have any questions.

We'll be putting some of these stories up on our site as part of our tribute to working-class animals.
