In the begging Luis was wondering what was wrong with Abigail. Abigail was sad and diprest.
Luis was asking his friend for help. He was asking if she knew something about dogs because Abigail was acting weird.
At the end Luis went running with his friend to see what was wrong and wile he was running he saw Abigail and saw that the reason she was weird was because she was going to have babies and now she had them and there 6 puppies.
In the beggining animals do all the stuff after something like an earthquake.
