Bernie found happiness in the house he shared with Marion and her pup, Alfred.The home was given to the Fallons by the grateful Matty Hatton, for finding and returning her poodle, Alyce. But there was a problem that had to be resolved. Alfred being a mixed-breed, was shunned by insensitive humans and pedigrees who considered him below their status. No matter how caring and perceptive Bernie was, the problem continued until the now deceased Saint Bernard, Wolf, visited him in a dream. The scholarly old canine explained that until the rebellious Alfred was reunited with his paternal father, Bruno, his future would suffer. Matty's senior reporter, David, who also was her suitor, suggested that in order to increase her newspaper's circulation, they should have the canines revisit Carson's Island and run a column on where and how Alyce, Bernie and Marion survived. However, they were unaware that Marion's former owner, Mike Warren, had planned to kidnap and hold her for ransom. The visit became the answer to Alfred's problem, when he finally meets Bruno on the island. However, the German shepherd was no longer the villainous canine, but maimed and helpless.Bruno instructs his offspring to avoid becoming what he once was.
During the visit, Alyce becomes lost in the island's forest and is found and held captive by Mike Warren. The dogs and humans search for and find where Alyce was being held. The villainous abductor tries to escape but is cornered and held by Bruno and his son. As the group prepares to return home, Alfred explains to his mother, that his father shouldn't be left alone. Alfred remains on the island to care for Bruno. Although Marion is teary-eyed, Bernie comforts her with the belief, that unless her son discovers his heritage, he would never be whole.
