Dog is too attached

Question
Hello, two days ago I found a little dog wandering on my farm and decided to take her in. She's timid and somewhat afraid of people. But she's been with me basically nonstop since then. She follows me around and even spent the last two nights sleeping in my bed. The problem is that I'm a college student and go back to class in a month and have to leave her alone in the yard. But whenever I'm away from her, she barks like crazy! My sister says to put her out in the yard for an hour a day before school so that I can train her to be without me. But how do I train her? How to I respond to barking? Thank you

Answer
Do you know how old the dog is, where it came from, what kind of dog it is? These factors will all play a part in how you train the dog. Without knowing this information it is hard to answer the question. You said she is timid, Does that mean she cowers if you correct her. Also, how likely is it that she is lost or do you think someone put her out. There may be someone looking for her.
