I just got to meet this dog in person.
He's not as tall as the pictures suggest.
He's NOT short coupled - has a very long back and long tail.
His leg bones and tail look thicker than in the picture (perhaps he filled out with a little more muscle after being in the kemmel?).
The rescue said that he was very fat, and already neutered when they found him! The mystery continues...
Right now, I am leaning towards adoption, and giving both our "Heinz 57" dogs DNA tests for their 'birthdays' - or I guess I should say adoption anniversaries!
Thanks to all the contributors!
