     After their 15-year-old dog Bailey died in 2007, Ron and his wife, Ann, looked for months to find the

right new pet. "I love dogs," says Ron, a worker at a health club in Waukesha, Wisconsin. "I can't imagine not having one."

     Finally, the couple spotted a young dog at the Humane Society in Milwaukee. His name was Oscar.

"He was very attractive," says Ron, 65. Oscar quickly made himself at home, sleeping on his new owners' bed at night.

     A diabetic(糖尿病人) for 25 years, Ron faithfully took his medicine four times a day and generally

had no problems. But on March 17, at about 3 a.m., he got out of bed to use the bathroom. Suddenly, he

fell down to the floor. "I must have taken the wrong amount of medicine before I went to sleep, because

my blood sugar was dangerously low," he says.

     "Normally, Oscar is very quiet and well-behaved," says Ron. "But when I hit the floor, he let out

sounds like a wild animal."

     "Honestly, it sounded like the dog from hell," says Ann, who was awakened by the sound." I didn't

know what the sound was. Then I saw my husband lying on the bathroom floor. He was cold." She ran

for the phone and called an ambulance.

     Ron spent several hours in the hospital. By 6:30a.m., he was well enough to go home. "You would

never suspect Oscar of any heroism." says his grateful owner. "He's a wonderful little guy. We are lucky

enough to own him."

     Even before Oscar's heroic action, the couple had given their pet a new nickname(昵称). "We felt the

name Oscar wasn't good enough," says Ron, "so sometimes we call him Eduardo"-more suitable, they

think, for their dog.
