The term "broke dog" is used pretty freely these days. Unfortunately, many don't realize where the term "broke" comes from.
In the old days, a dog was truly broke, it's spirit often broken in forcing subservience to it's handler. The dog's that could accept this treatment thrived and won, the dog's that couldn't, passed to the great beyond.
Harsh treatment is still commonly used to break a dog. Often because of time constraints. It just takes longer to "naturally" break a dog. But, I believe that the results are well worth the extra time and effort!
The average dog will show much more desire, ability, animation, and, love for it's work, after using a more natural breaking process.
Give the pupil enough birds, enough time, and firm and consistent, but also loving, direction, and we are rewarded with a truly natural and spontaneous partner in the field...
And, isn't that what we're all striving for?
