I think I like names that complement the traits and characteristics of the breed. Boxers are wild and crazy, boisterous, comical, loveable, yet also bold, fearless, tough, and all muscle.
I chose to name my current Boxer for the comical side of his nature - Bing.
Also for males, I like the names Kojack, Scooby, Ruffus, Chico, and Snoop. You could also go the ancient history notables route, ie Ceasar, Zeus, Homer, Tut, Orion, Moses, etc.
For females I like Tia, Layla, Delores ( yes, Delores

), Sheba or Shena, and Chakka ( prounounced ShawKa as in Chakka Kahn, or also ChalkA like chalk).
One thing to note, the name should be short and simple so your dog easily learns his own name.
