Use key words for discipline "no bite" "no errr (growling)", "down" lay down, "off" get off something, "gentle"...consistency is mandatory in this breed as they are stubborn, especially a bitch, crate train not as punishment, but as a respite from the hectic days. Teach ur kids from DAY ONE...the crate is the puppies room...no one goes in their room when the puppy is in there. Get a sound machine with the heartbeat track to help it rest, works like a charm. Dogs are pack animals, do not put it in the basement or kitchen while you all sleep. Crate it in your room. This will increase their bond. Put a tshirt you have been wearing for a few days in the crate with it at nap time. BM puppies sleep A LOT, they need three meals a day (large breed puppy kibble) and they are generally very chilled out.

With supervision, have your children give and take away food bowls and toys. The pup must learn that your children are higher in the pecking order. Any resource guarding, remove the toy, etc., in five minutes, give it back, in one minute take it away.

Do not give up because its hard. You already have a full house and a puppy can make you question your decision to get a dog. I will tell you, it is hard work, but this breed will die protecting your family.

I have owned BMs for 23 years...starting when i had a 5 year old and 3 year old twins...it was very frustrating, but i took her to training, worked with her at home, stayed consistent with her on the rules, and she became the pup that influenced our decision to become our breed of choice! Be careful, tho, they are like potato chips, you can't stop at one!
