So Malone just came bolting from the mailbox to come inside as usual... Only this time he slammed shoulder first into the metal door frame at full speed. He YELLED and held the leg up instantly. He seems to be okay now - a mild limp. I could not imagine HOW he was able to hit the frame with the door wide open... Until I remembered that his Embark DNA test showed PRA-PRCD. I think his night vision is starting to go. He will have to learn how to slow down.
