i have had many dogs but not a dobe . whenever i get a dog it ends up very playful even if it becomes a adult . whenever i get a pup my neighbour's kids play with it . so now ive bought a doberman pup i want her to be close to me . she is not gonna be just a backyard dog she is gonna be a active family member . all i want her to do his be protective (i.e) we have a fenced house i want her to guard (i.e) she should bark at others except my family and she shouldn let others enter my house without me . what can i do to achieve this qualities in my dog . she is still a pup ( 40 days old ) . how should i raise so that she wont be friendly with strangers . i ve seen dobermans in several places aggressively protecting its house and family without any training how can i raise my dog so that she will be like them . please advice me . i definitely dont want my new dobe to be a playdog .
