When we first got our Springer Spaniel, Gryphon (sounds like Griffin), there were 4 of us all fighting to name him.
Momma here settled the score, and went into an English Springer Spaniel's website to look at names of Champion Springers. It was a choice between Gryphon or Frigit and we chose Gryphon
My husband wanted so bad to name him HOMER!!
Maybe you could check out a Labrador website to get some ideas
Best of luck Dustybird
