Question: do the dogs die in where the red fern grows 2

Answer: Yes, Billy's mother and sisters are overjoyed with the prizes. He continues hunting. One night Old Dan and Little Ann tree a mountain lion, and it attacks. Billy enters the fight with his axe, hoping to save his dogs, but they end up having to save him. Eventually, they kill the mountain lion, but Old Dan is badly wounded, and Billy finds his intestines in a bush. He dies late that night. Billy is heartbroken, and Little Ann loses the will to live, stops eating, and dies of grief a few days later on Old Dan's grave. Billy's father tries to tell him that it is all for the best, because with the money they received from winning the championship hunt, they can move to town. He goes to visit Old Dan and Little Ann's graves and finds a giant red fern between them. According to Native American legend, only an angel can plant one. He and his family look at it in awe, and he feels ready to move on knowing that his dogs are always going to be remembered.
