I have met a working border collie before, my grandparents had one in Montana. It was an awesome dog! Addressing the consistency in training with a family of 5. Everyone is on board with getting a dog, and they know that consistency is key. I will be primarily responsible with training the dog, but they will all be under my instruction so we can make sure bad behaviors cease. I am considering other breeds, but the border collie is my first choice. People have been suggesting labs, but I have never come across a lab that can keep up with me on runs (the dog I get will not be limited to a running partner). The other breeds I'm considering are siberian husky, Australian shepherd, and open to other ideas. I am not opposed to a breed that is challenging to train, usually this means the reward is also higher.
