‪@KrustynLara‬ in order to help the sheep feel comfortable about a dog or dogs working on the border I have been progressively giving them smaller and smaller paddocks. This new paddock has plenty of food in it, but, the size brings the dog on the border a tiny bit closer than yesterday. Soon they'll all be reading and trusting each other. You should note that the dog is experienced and so it is the sheep that are moving a little closer to the border. When it is the dog that is new, it is a different emphasis.
