Congrats on the new addition!!!
Something you should think about is that you dogs name should be 2 syllables no more, no less. This is because most common commands are one syllable (sit, Stay, come, down... etc) and it's easier for them to reconize their name.
(this comming from a woman with a dog named Sierra My hubby picked her name)

Ruger (sounds like Roo-ger)
