单项选择题

Mr. and Mrs. Macgregor live in a village near Inverness in the North of Scotland. One morning, they found a dog in their garden. They took the dog in, gave it some meat, and watched it go into a corner and go to sleep. They decided to let the animal stay overnight, and to look for its owner in the morning. Then they left home to pay a visit to their daughter in Inverness.
They came home about eleven. As they opened the front door, they were welcomed by a snarling (狂吠的) boxer, standing with bared teeth. Any attempt to calm the animal met with angry barking. Soon the neighbors were awake, and came out to offer helpful advice.
Then the fire brigade was called. They arrived at midnight. But all their attempts only made the animal more violent. They couldn’t get near it. The fire brigade gave up and called the police. When they arrived, it was one in the morning, and nearly all the villagers were gathered in the Macgregors’ garden. The police thought about it. They advised the dog should be shot.
However, someone went for an expert dog handler. This expert arrived at two in the morning with a huge Alsatian. He said. "This won’t take long."
But it did. The two animals stood and stared at each other. It was a draw.
Then a vet (兽医) was sent for. By the time he arrived, it was 4 a.m. He borrowed a rope, made a lasso (套索), and threw the loop over the boxer’s head.
He dragged into the garden, stuck a needle in it, and put it to sleep. The police removed it.
Macgregor said. "This animal will make a wonderful watchdog. But the new owners must be prepared to stay indoors for a few days until the dog gets to know them." Who finally succeeded in keeping the dog under control

A. The vet.
B. The fire brigade.
C. The police.
D. The expert dog handler.
