premise: How to train big dogs<br>Start early. Although this may not always be an option, starting the dog training process when your dog is less than 1 year old is ideal, especially when it comes to large dogs. Plan to begin training your dog as soon as you bring it home, which may be as early as 8 weeks.
hypothesis: Plan to train your St. Bernard 6 months after you bring it home in order to be successful.
reason: The earlier you start training the better but there is no set timeline beyond that.
