Barbaro Watch.

Barbaro has progressed so well he is now being hand-grazed outside of the veterinary hospital.

He is gaining weight and has a good overall attitude, according to Dr. Dean Richardson.

Barbaro's intelligence may be helping him in his recovery.

More about Barbaro's venture outside:

"That's the first time he's been outside since we brought him in," said Gretchen Jackson, who bred and campaigned Barbaro along with her husband, Roy, in the name of their Lael Stables. "Dean took him out, and he just stood there for easily five minutes, looking at the scenery like, 'Oh my God, I'd forgotten about all of this.' He just looked around for some time before he put his head down, and then he ate away and was probably out for a good 20 minutes, enjoying himself. It was just the nurses out there and maybe a few vets and I think there were quite a few tears shed to see him do that."

And:

"It's a big step just to know he feels good enough that you can take him out of the stall and walk him around like a normal horse and he eats grass like a normal horse," Dean Richardson, chief surgeon at the New Bolton Center, said Monday. "That doesn't mean he's healed. It just means things are going well right now."

The 3-year-old had made only a couple of brief walks back and forth from his stall to the surgery room at the University of Pennsylvania's New Bolton Center until last week. Now Barbaro is walked daily for about 15 to 20 minutes in a secluded area not far from the George D. Widener Hospital ICU.

"I thought he was thrilled the first time he went out," Richardson said in a telephone interview from New Bolton. "He just seemed very happy to be out. You can tell he's looking forward to it every day. It's absolutely normal. Horses love to be outside, obviously, and he's pretty excited about it."
