The most beautiful dogs in the world are the ones that are yours.
Sammie is adorable; I have a great fondness for houndy types. Don't worry about what others think, even if they think she's a boy. I doubt she's losing any sleep over her gender identity.
I have females named Argus and McKeever. People always think they're male. I love my dogs, and I love their names because they fit them. If other people don't "get it," oh well.
