Lost dogs in Librilla

Could everyone keep an eye out for our escaped dogs. They escaped on Friday night from our finca in Librilla. They are brothers, 3 years old. One is black and white, one is black, they are cross collies. They are lovely dogs, George, the black and white is smaller and quite a nervous dog, Sam the bigger, black dog is more placid. Where we live is remote, surrounded by lemon groves. They have never escaped before, are always on the lead when they go a walk. We have told our Spanish neighbors to keep an eye out but anyone in our area if you could do so as well. Thank you
