Andi Davise, 49, regularly crossed the trail through the Phoenix Mountains Preserve with a few other hikers before sunrise. This morning, however, she met nobody and heard only the sounds of animals.

Some time later, Andi got to the steep slope(陡坡), she climbed up to the top by using her hands. When she finally reached the top, she noticed a dark shape several inches from her left foot. She was frightened and then looked carefully. "It's a dog and it's dead." she said to herself. It took her a few seconds to realize that the dog's eyes were open. A thin, dirty bull dog was looking at her.

She greeted in a low and soft voice to show she was friendly. The bull dog shook when he heard her voice.

Andi inched closer and dropped some water into the dog's mouth. He tried to stand up but failed. Something was wrong with his left front leg. Andi pulled out her phone to contact her husband, Jason, but he didn't respond. She knew that if she didn't carry the dog down the mountain, he would die.

She carefully put her arms under the dog's body. He was so weak that he fell into her chest.

Andi had great trouble going down the steep, rocky mountainside with the 50-pound animal in her arms. Even her arms and back started aching, she didn't give up. The trip up had taken 30 minutes while going back down took twice that.

Andi's husband received her messages at last. He and their son, Justin, jumped into the car and drove to pick up Andi.

Later that morning, an X-ray showed that the bull dog was badly hurt, he was likely to lose his left leg.

A few days later, the Davises returned to the animal hospital. "The first thing he did was to give me a kiss, then he went right to my son." Andi said. They named the dog Elijah and brought him home that day.
