We took him to a specialist in the VA area
http://www.southpaws.com
We were impressed!
In the end, he was diagnosed with the following:
LEGG-PERTHES (LEGG-CALVE-PERTHES DISEASE or ASEPTIC NECROSIS OF THE FEMORAL HEAD).
So... the little guy has surgery tomorrow morning. They are keeping him overnight, and then we get to pick him up on Wednesday. Luckily, that is my day off.
We're worried.... so say a prayer! We're going to contact the breeder as well, as it is a recessive gene obviously in their gene pool.
