What does Cosmo mean?
Modern: Relating to the universe or cosmos.. Cosmo is derived from the Greek word 'kosmos', meaning 'universe' or 'order', often associated with the cosmos.

Is Cosmo a good dog name?
Cosmo has not been formally rated for calling yet. As a rule of thumb, one or two clear syllables work best for recall. With 2 syllables, it is quick to say — a practical length for recall.
Before you commit, say it out loud a few times and check it does not clash with a household name or a training cue like "sit" or "no".
