I will be picking up a great pyrenees female pup tonight. Shes about 8 months old. They have told me shes been around other dogs and cats and does just fine, but they dont have any other animals. So theyre not sure how she would do with the chickens. This will be my first time getting a dog for guarding anything. What is the best way to introduce her to the chickens and get her started on guarding them? ANY info would be a great help! Thanks.
