She looks like a nice puppy. It is unrealistic to expect a year old pup to be performing LGD work unsupervised. Imagine 8-10 year old child asked to do the adult's work (it is an equivalent of your 1 year old pup). The olny way you can leave an underaged dog with livestock is if you have an older dog(s) to watch over and teach the pup. I am sure she has the right instincts, but she needs some skills to go with these instincts and right now she is young, rambunctious, playfull, and a little bored puppy. She is also the only LGD you have, that means she craves attention from humans or another dog with same intelligence level as LGD. Since you don't have an older LGD to work with her - it should be your job. Simply take her with you while you are doing the farm chores (on a long lead) and prase heavily when she acts as expected, correct with your voice and a leash jerk when she acts silly. Make sure you provide her with play time, to have some puppy fun and socialise her with family. I think Sars are very similar to COs and I can tell you that COs do not need to be bonded with the livestock. They use territorial perimeter guarding style, that means anything inside their territory is guarded. The dogs also bond well with owners and the more they bonded with you, the more they understand your actions and wishes and the more they want to work for you. I have had adult dogs that never seen livestock untill the age of 3-4-5 years old work perfectly well protecting the animals, and I have my puppy owners who are farmers raise the dogs in the house, but taking them along for daily chores untill they are used to daily routines, and reliable enough to be trusted. Usually the dogs around 2 - 2.5 years old mature and express desire to stay out with the stock, rather than coming back to the house. It is natural transition for them as they grow up and take responsibility for the things around them. I know most people think that a puppy should be left with the livestock and not socialised with people to be effective, and I think GPs work like that, but it is not so for COs and I suspect, for Sars. It has been my experience. My dogs work with sheep and chickens, but they also taking turns living in the house with me and cats. They enjoy human companionship very much.
