AFAIK:
Yes, officially he broke his shin. But, don't be fooled. He suffered a small fracture in the center of the tibial plateau of his right shin. This is a non-load-bearing area: this means that although he was in pain, it wasn't so bad that he could no longer walk or ride. Such a fracture takes a short time to heal, especially compared to a normal tibial plateau fracture.
And although I'd never say no to pictures of Alberto and his dogs, I fail to see how the image you posted is relevant in this discussion.
