Johnny's latest update

He started Navigator this AM. He's being carefully watched for adverse reactions. It's a pretty potent drug and about 1/3 of horses have severe reactions to the drug. He still has fairly mild elevated digital pulses, but his feet seem cooler. He didn't seem depressed today and enjoyed a 20 minute walk outside in the snow (considerably more than I did). He's wearing SMB II's on his hind feet for support. The neurological signs are still persistant, but at a lesser level than he was even a day ago.
His outlook is cautiously hopeful.
