One of my friends has one.
Good points..very handsome dog. little to no shedding. Likes people.
Bad points...almost untrainable inspite of experienced owner. somewhat dog aggressive in spite of extensive and careful socialisation. was difficult to house train. Little or no recall. stubborn. cannot be trusted around small furries/cats. needs grooming every 6 to 8 weeks. has food intolerance's and sensitive skin...and this dog came from a responsible and well respected breeder to an experienced with dogs home.
