An extension that is aptly named - it will provide you with dogs, nothing else. There is no purpose to this extension beyond making you smile one additional time each day. Upon installation, the extension will add a small browser button. Clicking it will produce your daily dog. It will never introduce itself unless you click the button. You can click the button as often as you like, but a new dog will only appear overnight. Each day has its own dog, like a picture calendar.
