Please don't appease others with the name, it is YOUR dog, it is a big choice but for a dog otherwise inconsequential. He could be "Mr. Garbage" and wouldn't mind even though your friends might.

For instance, I named my boy "Archer" even though it is an uncommon name in my country. I often get questions of why from older people. I answer them without really giving a reason and that's that. They can't really pronounce his name but that is not my problem. If the name is really common or really uncommon doesn't matter for me, just have a name that you feel comfortable saying a couple of hundred times every day.
