I for one really like the name and URL and don't mind the name collision.

It's something that is bound to happen. There are a finite number of words, names, and spellings to make use of.

Not really, because it doesn't need to be a real word or an existing name. It could be Rexfus, for example. Even the dot com is available, and as a combination of Rex and Rufus, still dog inspired.

Rexfus is great!

It receives RSS Feeds, so:

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

That's way harder to pronounce.

Just adjectify it. https://www.whois.com/whois/rufus.ly
