You can add 'Happy Dog' to the list of PC names. 
A friend gave me a puppy once, and it took a couple of days for us to come up with the name (Smokey).  When I told him, he breathed a sigh of relief. "Now that she has a name, I know you're gonna keep her." 
This dog is now 14 and gets along with the aid of a cart, as hip displasia has taken her back end.  But no matter what, she is always a happy dog. 
And the name just seemed to fit my '90 PC, so 'Happy Dog' it is.
