I choose the picture because it looked a little like Sadie (but no it is not dalmation ) I'm not sure I buy what they say the mix is, although they way it is sitting does make it look like a long dog.
(subtle hint)

Riley's face reminds me so much of Sadie. He has a lot of similar expressions. All your dogs are beautiful, but Riley is really the one I just am in love with What can I say, I am biased for the big black doggies.
