Pet Care Needed - Full-time / Part-time

I'm looking for a great sitter for our 2 dogs in late June/early July for 12 nights. Our girls are 9-year-old and are sisters but couldn't be more different - one is high energy and wants to play while the other is much more relaxed. They can be on their own for about 6 hours so there is some flexibility but overnight stays are required. Responsibilities include feeding, giving medications (put in food), exercise and play. Non-smoker preferred
