Fetch!

'Fetch!' is a Chrome extension for everyone! Stressed, sad, or even happy, 'Fetch!' has got your back. On whichever website you're browsing, activate 'Fetch!' and you can fetch yourself a photo of a dog to display in your browser. Get a dog from a random breed, or from one of the breeds offered in the dropdown. Once you've had your fill, get back to your previous display by simply closing out of the image.

Note: Fetch! does not work in a "New Tab." You must be in an actual webpage for Fetch! to function properly.
