April's parents were dog breeders and their kennels were often filled with a litter of puppies. April helped care for the dogs by bathing them and giving them the best food and water.
April's class had also been learning how to care for animals in their science lessons, so she was thrilled when her teacher announced a field trip to an animal shelter. The shelter manager, Rachel, led the class into the kennel area where dogs and cats sat along opposite walls of the building. April was stunned by what she saw. Some dogs looked like they had been starved before coming to the shelter.
"What happened to these dogs?" April asked.
"These dogs are here because their owners did not care for them properly," Rachel replied. "We try to keep the animals healthy so they can go to good homes. If you know someone who wants to adopt a pet, please tell them about our shelter."
April decided to take action and she printed flyers with information about the shelter. April's parents handed them out to people who bought their puppies. The following day April received permission to post a flyer at her school. That afternoon, April received a phone call at home.
"Hi, April, this is Rachel. I wanted to thank you for creating flyers for the shelter. Our adoptions have already started to increase!"
"You're welcome! I just wanted to help rescue the puppies."
