I started a new book called Sniffer Dogs by: Nancy F. Castaldo and I learned that if somebody has a guide dog and the owner dies, the dog helps get them to the hospital. There was a boy and his dog Eli, for his 20th birthday they went to Afghanistan. While they were there, the boy got shot. Eli and and the mom went to him and got him to the hospital as fast as possible. At the hospital, they found out that he was oficially dead. The mom now wears a necklace with a picture of her son and Eli.
