We recently paid our pet "sitter" $250 a week----but we have 6 dogs. She stops by twice a day to visit, feed, water, and give them their medicine and follows special feeding instructions for some of them.
She also "cleans" up their accidents as needed (they stay on an enclosed porch) and washes towels, bedding, etc. She runs them to the vet or groomer if needed (as she works at the vet during the day). Very reliable and loves dogs. She did a great job the four weeks that I was gone.
Compared to the professional dog sitters for the number of dogs that we have, this is very reasonable and I feel very comfortable leaving the dogs in her care.
