Never strike or yell at a puppy if she disobeys you. Bernese Mountain Dog tend to be very mild tempered and obedient but they, like all dogs, will take some time to train. Hitting it will only make the puppy fear you and confuse her — never strike your dog. If you in the middle of a training session and she doesn't fully understand, do not become impatient and scold her. After all, the puppy or dog is only learning.  If you find that you are losing your patience, step away from the dog and try again later. Bernese Mountain Dogs are extremely affectionate and want to please — scolding or punishing may have an extremely detrimental affect on your Bernese. Focus on positive reinforcement instead of punishment. This could be with a tiny tasty treat or just praise as the dog develops. If the dog knows he gets a treat for good behavior, and bad behavior is ignored, then he is likely to reproduce good behavior it was rewarded for.  When you catch your dog or puppy chewing or destroying something he shouldn’t, remove either the dog or the object from the dog and distract him with something it can “destroy” or chew on, like a toy. Then praise him for chewing on the right thing — the toy. Keep a bag of treats in a Ziploc bag in your pocket or in a “fanny” type bag at your waist. This means you will always have a treat handy. You never know when an opportunity to train will pop up during the day! During the first few weeks of training a puppy’s attention span is short, usually less than five minutes. As your puppy gets older and starts to associate training times with pleasant interaction with you, the training time can be increased. You will know the dog's attention span is increasing when the puppy focuses more on the training sessions than on wandering off and playing. You can teach your puppy commands from the moment she arrives home. Keep training sessions short (less than five minutes) and practice three to five times a day.  Your Bernese Mountain Dog should be able to learn a variety of commands. Start with leash etiquette and commands that limit bad behavior, and move on to more specific commands.
