I adopted Titus about a year ago. He was difficult to work with at first, due to having anxiety from previous owners. I crate trained him, taught him tricks, and taught him lessons in obedience. He used to only prefer dogs,due to living in a shelter with a variety of breeds most of his life. After his year with me, he is now a lovable mutt who loves all dogs and humans. He does not bark or bite. Although I do not have a lot of dog sitting experience, I have dog sat for friends and family. If your dog will be staying with me, my dog is housed in doors, which means yours will be too. I am a very energetic person, so exercising and walking will never be a problem. A bonus for those venturing on vacations: I am student at UCSD and am out of school for the winter from Dec 6-Jan 2.
