He sounds like one of my friend's dogs and they named that one Duke. I was all for the name Shadow though, but they said it sounded too wise for a dog that chased its tail all day so I would go with Duke. Here are some more name's if interested. 1. sammy 2. Frisky 3. Luke (Leukocyte-white blood cell)-that one's from my Aunt 4. Max or Maxwell. Good luck on the name.
I love indian names. My german shepard dog was named Shawnee, & my collie's name was Sundance, Sunny for nickname. I also like the name Bear & Odie or Ottis.
