I've been reading about LGDs and Great Pyrenees. I've read threads on this forum, and I've read library books about the topic. I would really like to get a puppy and train him/her to be a guardian for my chickens, However, everything I've read about the dogs that are bred to protect livestock is that they need a tall, strong fence because they are prone to wander away. We have the large area - 90 acres, but a fence is not feasible around our house. What are some breeds that can be trained to be a great LGD for my chickens - but won't be prone to wander off. We already have a black lab that wanders the acreage - but doesn't go off our property. He's too attached to my husband to be a good LGD, though - although he does do some guarding of the property. He's generally indifferent towards the chickens. I also don't want a huge dog. I'm willing to put in the work to train the dog, and I understand that it'll take a year or more to get any dog to the point of trusting him/her with the chickens. I'd like a nice average-size dog that can be trained, will keep the chickens in the yard when they are out of their pen, and will chase off any stray raccoons, skunks, bobcats - and will want to stay close to home. Any suggestions?
