The Petfinder Listings plugin takes advantage of the Petfinder API and can be integrated into your site without coding.
You will need to generate a free Petfinder API key on Petfinder here: http://www.petfinder.com/developers/api-key.
If the list is not working after correctly entering all your Petfinder Listings Settings and the page displays a status of 'shelter opt-out', make sure your Petfinder account is set up to share data through Petfinder's API. To do this, log into your Petfinder account and click on the Organization Info tab. Look for the box labeled 'Share Pet List' and make sure all checkboxes within this box are selected: Please share my pet list with all third parties, Partner sites & Petfinder API users.
This plugin generates generic HTML and includes a stylesheet to position the elements. To style, override CSS in your theme's stylesheet. You might need to add !important to each style.
Petfinder does not return video information through their API, however if you have a video on YouTube you can paste the video embed code in your pet's description to display the video through the Petfinder plugin.
