Dog sitting?

I think a dog sitting for the summer. I'll just take care of them for a few hours as when the family goes on a day trip or maybe a theme park for the day. They will be in an enclosed area outside w / grass in the house when it rains. I will walk and play with them too. How do you think I responsible?

I pets, but dogs remain in their own home. I'll make a visit for 1 hour, or two visits of 30 minutes. I charge $ 10.00 per day, but it depends on how nice a neighborhood of your work
