Bill Clinton had a Labrador(拉布拉多) named Buddy and a cat named Socks during his time as the president of the US. The pair often fought. Clinton once told reporters that Buddy would sometimes sleep next to him when his wife was away. “He is my true friend,” he said.
But more than dogs and cats lived in the White House. The wife of John Quincy Adams, the sixth US president, had silkworms. Therefore Roosevelt, the 26th president, was famous for his many pets. His six kids had snakes,dogs,cats,birds,guinea pigs and more.
Donald Trump is the first US president in more than 100 years not to have a pet. A Joe Biden presidency means the return of a long tradition of pets in the White House. The president brought his two German Shepherds (德国牧羊犬), Champ and Major, along with him when he took office in January.
