My male, Spike, was named that because I had to think of a name quickly. His name was "Buddy" when we got him, but we already had a dog in the house that was named "Buddy", so Spike was the first thing that came to mind. He gets called Chewy frequently though because when he really wants something, he sounds like Chewbacca from Star Wars. LOL
Star was named for the marking on her chest. She only has 1 little mark & it looks like a star.
Denali just sounded good. LOL Also, denali means Mt. McKinley & her markings kinda look like mountains.
