Fun topic! I've had two dogs in my life. The first dog was a shelter dog, his name was Turbo. The staff that worked at the shelter called him that because he was a Jack Russell/Maltese cross and he was SO hyperactive! He could run and run all day long and I honestly don't think he ever seemed tired! We just thought the name was a perfect fit for him, so never ended up changing it. It's funny to me how sometimes the names that shelter staff give the animals there are just spot on in terms of describing the pet! I still miss that dog...
My current dog's name is Banjo. We just chose that name partially because it's cute, and partially because it has Australian origins (we have Australian family members!) There's a very famous Australian poet by the name of Banjo Patterson so that was part of the reasoning too. I think it fits him well, though! It was a bit of a random choice, but it's surprising now that we simply couldn't imagine any other name for him!
