My boyfriend and I adopted a red bordie collie from a rescue place four months ago. I had a border collie before, so I knew what to expect as for level of exercise and stimulation. But what surprises me is his inability to be left alone in the house. He tears things up when we leave, and as a consequence, someone always has to be home with him. We love him to death and will not give him away, but sometimes, he drives us crazy.
