Answer:
He cries.
Step-by-step explanation:
"Where the Red Fern Grows" tells the story of Billy, a boy who dreams of raising two hunting dogs of a breed called red-bone. These dogs are very expensive to buy and Billy does not have the money since his family has a low economic condition and are going through the problems caused by the great depression. However Billy does not get discouraged and does not give up on the dream of owning the dogs and that is why he tries to get several jobs and save all the salary he can get. He works hard and collects the money for two years, until he has enough to buy the dogs. When he finally manages to buy them and holds the puppies for the first time, he cries a lot because he has managed to make a dream come true.
