Colby

Colby is an Old Norse place name meaning 'coal settlement' or 'dark village,' from kol (coal, charcoal) and by (settlement, farm). In the US it is also associated with Colby cheese, the mild Wisconsin variety — a food connection that adds a warm, American flavor to the name.

Colby strikes a nice balance between rugged and friendly. The Norse etymology gives it some grounded history, but most Americans today associate the name with its breezy, all-American sound — the kind of name a laid-back golden retriever or a cheerful lab would wear perfectly. The cheese connection is not a liability; if anything, food associations tend to make pet names feel more affectionate. Colby works for male pets with an easy, sociable nature and a slight athletic edge — good with kids, good with strangers, good with life in general.
