Reva is very, very beautiful Michelle!
By the way, I have a black labrador retriever myself - his name is "Gus". We didn't choose that name, as we adopted him from a local humane society and didn't know how long he'd been "Gus" - so we just kept the name, since he'd been shunted around from shelter to shelter.
He has been a real challenge... and makes Marley of "Marley & Me" look positively tame.
Meanwhile, I am really enjoying seeing these pictures of your Reva. She is just gorgeous. You have a very beautiful new dog. Her face and her expressions are soulful and intelligent. Plus, her fur is dark and very glossy.
Imagine the most friendly eyes ever, a really cute and pretty face, complete with the darkest and glossiest fur. That's your Reva. She's an absolute beauty.
Here's hoping the adjustments and training are going well.
