Hi y'all! After losing several chickens to a neighbors dog and a couple of strays, we decided to get an outdoor dog to train for protecting our animals/property. A coworker gave us a Mastiff/Great Pyrenese cross. She is about 11 weeks old and I'm wondering if anyone has advice on how I need to train this girl!? Right now we just have chickens but we're planning on getting a few goats in the near future. Would it be better to get them right away so that she's raised around them? I'm planning on training her on her boundaries over the next several weeks as well. Any advice would be greatly appreciated!
