Reggie's given name was Damu. The day before we were to meet him, Scott and I were wondering what Damu meant, so I did a quick Google search on my phone.
It should be no surprise that the owner of a poorly treated, intact male pit bull gave him a "name for the Bloods to call each other," according to urbandictionary.com. Damu "comes from a Swaheli word meaning 'blood-like.'"
Damu is possibly a reference to the red color of his coat, but it isn't a term I feel comfortable saying very loudly in our neighborhood. "Reggie" seems to fit just fine. He learned his new name quickly and responds eagerly when called.
