One wants to introduce Livestock Guardian Dogs such as the Great Pyrenees, or Kangals to the animals, poultry they are to protect. As the LGD gets older the protection instincts set in and whatever the LGD regards as family is protected. The LGDs learn the animals/people/birds are "part of the family" and will protect them. This video shows one of the ways to introduce them. The mother goat is removed as the instinct of the mother goat is also to protect and her head butts could harm the puppy.
