Prince was a dog. His owner, Julie, was an exchange student from Singapore. She had found him lying in the street, cold and hungry. _36_ her apartment’s no pets rule, she rescued him and took him in. but after several weeks of hiding the __37_ dog, she brought him to our house.

“Just for a couple of weeks,” she  38  me, “until I can figure something else out.”

But after several weeks, Julie asked us to keep her dog forever. Of course, she didn’t have to push too hard  39  we had all fallen in love with this little dog.  40  , we weren’t too crazy about his name. “Prince”  41  so formal. It was more like the  42  of a German shepherd (德国牧羊犬). Although we all  43  to come up with a name more fitting, we seemed to be stuck with “Prince”.

Before long Prince showed some of his princely  44  to our family. It started when our younger son Luke was sick in bed. Prince didn’t usually go  45  where the boys’ rooms were. He usually  46  to me like glue since I was the one who fed him. But on that  47  day, when I went upstairs to check Luke’s fever, I found that Prince was  48  beside my sick boy. He didn’t leave Luke’s side until Luke began feeling better.

The same thing happened  49  . Whenever anyone in our family was sick, Prince would be right by that person’s side  50  it was his job to take care of them until they recovered. It was incredible to see this normally  51  dog put aside his romping （玩耍的）needs to display his  52  for a sick family member.

Our little Prince lived for nearly sixteen years. He  53  loyal to our family the entire time. Even in his final days, when he was in pain, I knew he would  54  his life for any of us. By then we had all realized that he had been named  55  -- for he truly was a Prince among dogs.
