Bark, Rowdogs, Bark!

What did the one and only Rowdog on planet earth, who was waiting online to get his copy of "Here I am", say to the other Rowdog standing beside him...??

(Meh..) Less-than 350-K WW: If a Rowdog barks, and no one cared to listen, did she really bark?

Being fired..er...(sorry)..not wanting to return to X-Factor U.K.: What did the Rowdog do once she actually caught the car? (..Still nothing? Hint?) ..Well, what did the Rowdog do once she actually caught her tail?!
