Lenny may have lived a fairly secluded life in the past and while he thoroughly enjoys human company he did lack a few social skills with other dogs, and this would be because he was unsure of himself. This has certainly changed now and he loves a game with other canines and would most likely live with a playful female mate
He is searching for a home with someone who has experience in training dogs as he is still young and in need of some direction. He will do best in a teenage/adult home, and if he is not to live with another canine, he will definitely need a human companion who is home most of the day
