Brownie and Spotty were neighbor dogs who met every day to play together. Like pairs of dogs you  36  find in most any neighborhood, these two loved each other and played  37  so often that they had worn a path through the grass of the field between their own houses.

One evening, Brownie’s family  38  that Brownie hadn’t returned home. They went looking for him with no  39 .Brownie didn’t appear the next day, and, despite their  40 to find him, by the next week he was still missing.

Curiously, Spotty  41  at Brownie’s house alone, barking. Busy with their own lives, they just ignored(不理睬)the  42  little neighbor dog.

Finally, one morning Spotty  43  to take “no” for an answer. Spotty followed Ted about, barking strongly, then running towards a nearby wood, as if to say “ 44  me! It’s urgent!”

Finally, Ted followed the anxious Spotty. The little dog led the man to a  45  spot a half mile from the house. There Ted found his beloved Brownie  46 , one of his hind legs stuck in a steel leg hold trap. Horrified, Ted now wished he’d taken Spotty’s earlier requirement  47 .Then Ted noticed something quite remarkable.

Spotty had done more than simply  48  Brownie’s human owner to his trapped friend. In a circle around the  49  dog. Ted found some dog food---which was later  50  as the remains of every meal Spotty had been fed that  516  !

Spotty had been visiting Brownie  52 , in a single-minded quest to keep his friend alive by offering his own comfort. Spotty had obviously stayed with Brownie to protect him from being hurt, snuggling(依偎) with him at night to keep him  53  and touching him gently with its nose to keep his spirits up.

Brownie’s leg was treated by a veterinarian and he re-covered. For many years afterward, the two  54  watched the faithful friends frolicking(嬉戏) 55  chasing each other down that well-worn path between their houses.
