properly fed

This paragraph is written in another version. Please help me correct it. Thanks!

One day, my friend Sandra was walking home from school. Suddenly, she saw a strange yellow dog with wings lying prone on the ground by the roadside. It was injured, and it was weak and hungry. Sandra wondered if the fairy dog would die without her help. She took pity on it, so she took it home and fed it some food. After the dog was properly fed and cared for , it gradually fell asleep. To Sandra’s amazement, she found that the dog’s wounded wings were healing up the way it should inch by inch while sleeping. Hours later, Sandra was about to go to bed, so she walked to look over the dog. She saw many fairy puppies flying around in the room. They were the yellow dog’s babies! Now the yellow fairy dog was a mother and it looked satisfied with its babies. When Sandra got up the next morning, she ran to the room where the dogs stayed the night before. Much to her surprise, all the mother and baby puppies had gone away. Sandra was a little depressed, but she knew that it was the best ending for all of them .
