I had 3 dogs throughout my childhood. In college I adopted a 3 month old German Shepherd puppy and he's been my best friend ever since. My dog and I have been inseparable since I adopted him. He's 4 years old now, and loves the company of other dogs. I figured dog sitting might help him feel some sort of companionship that he doesn't have from a younger brother or sister. I would treat your dog as my own, love and care for them, and keep them well entertained. I'm a huge dog park guy, so I would most likely take both our dogs to the park to get them exercise as well as tire them out. I can crate my dog as well if it makes you uncomfortable. Pretty easy going
