If you haven’t created your personal portal yet, please email us at team@dogagingproject.org. We will delete your previous nomination, after which you will be able to submit a new nomination through our website at dogagingproject.org. Once you have set up your personal portal, your research profile is linked to your nominated dog and to your email address, and we can’t switch your enrollment to a different dog. If you have completed the Health and Life Experience Survey and your dog is a member of the Dog Aging Project Pack, you can log in to your personal portal and use the purple button that says “Report a Major Event” to tell us that your dog is no longer a member of your household.
