DIY Pet Paw Prints - Could do something like this as a remembrance when beloved pets pass on. What a cool thing to do if you get them from puppy to older. Use them as a yearly dated holiday ornament (keep their dog tags / cat tags as well)
Company makes stuffed animals to raise funds for shelter dogs. Send in a pic of your dog and you will get a stuffed animal that looks just like it. You can even "adopt" a stuffed animal inspired by real shelter dogs.
