I would venture to say most people on here don't have a real need for a true LGD. Unless you literally want a dog that stays with your livestock 24/7, then look into a LGD from proven LGD breeding lines.
As far as having your pets co exist peacefully with your flock, that depends on the individual dog AND training. An adult, pet LGD that has never been around chickens or livestock isn't any more likely to guard them or be safe around them than your **average** dog.
Now some dogs will be more likely to cause problems, high drive terriers (for example) would be hard pressed to be safe around small, erratically moving birds. Most dogs with proper training will be safe around your flock under supervision. You just have to decide if you want to put the time into training and risk the possibility of injuring your flock of something goes wrong.
Personally I have 4 Dobermans. They are ALL fantastic farm dogs in their own right. My 8 year old male show dog and my 2 year old female show dog are great ratters. My male has brought me as many as 15 rats in a 10 minute time frame when we went to a friend's farm that was overrun with rats. While he is awesome with people and dogs of all sizes, he is NOT cat, small rodent, avian, or livestock safe. But he is impeccably trained so under supervision, it isn't a problem. My 2 year old female (I show dogs btw so I am trying to remember to say female and not b**** but it is hard, so please excuse me if I slip up) is a great ratter but was on the road with a professional handler for a year training for and attaining her AKC Championship, so her training is extremely lacking right now, so she is on leash around any new animals right now until I can fully assess where she is at after being gone a year and getting her training under control.
My 4 year old retired show girl is safe around anything. She did not inherit her father's drive for hunting ANYTHING except squirrels. My 11 year old rescue is safe around EVERYTHING. She has raised anything from kittens, chickens, pet birds, squirrels, opossums, deer, you name it.
I think everyone should read the blog being referenced because we can **all** benefit from it (either by learning something new or seeing something we have known from another standpoint). That being said I would never leave any animal around my livestock (no matter what breed or training) without knowing that **something** could go wrong because at the end of the day, they are animals. I also do not condone leaving small children alone with any animals unsupervised (livestock or pets) for the same reason. They are animals and most children can not, or just don't bother, reading signals well.
At the end of the day you must remember they are animals, they have instincts, and instinct will always trump training if pushed to a certain point
