Dog Sitter Needed

An hourly fee is not appropriate for our circumstance of housesitting for two dogs. There would be varying hours of care, and we want someone to sleep overnight. We have two Schipperkes - both are show dogs. Female 4 years old and male 12 years old. We are looking for someone who can stay at the house with the dogs while we travel to dog shows. They would be let out of their crates in the morning for an hour or so, then one can stay outside and the other stays in the house. The house dog would need to go out to potty mid-day, and then the sitter would return to stay for the night around 5:00-6:00 p.m. (?)
