Cairo: Hero dog or hero sandwich?

{Having survived the raid on Bin Laden's compound, combat dog Cairo had a close encounter with his dog-muncher-in-chief}:

President [Obama] asked to see Cairo, the dog that had accompanied the SEALs on the raid. The SEAL team commander warned the commander in chief, “Well, sir, I strongly advise you to have a treat, because this is a tough dog, you know.” Cairo was presented to Obama, although a presidential petting was discouraged and the dog was wearing a muzzle.

{No mention if the President was muzzled as well...}
