That was me trying to be clever choosing a quintessential dog name, as the application "fetches" the paper (rss feeds) for you :D . I was playing around with the name Rover and a few others for a while as well, but went with Rufus for the cheap .news TLD

Rexfus, a combination of Rex and Rufus, is available (including the dot com) and would be easy to SEO.

Are these names somehow related to each other? Our childhood dogs (RIP) were Rex and Rufus.

I agree with Nexxxeh; Rexfus is a good choice.

  Rexfus => Receives for us.
  Rexfus => Rx       F   Us
  Rexfus => Rex      Fus
  Rexfus => Rexfus
