Pet Care Needed - Full-time / Part-time

We have a 6-month-old puppy who needs a playmate. He is still being potty trained and can only hold it for a couple of hours or so. He needs to be played with and walked. He has a 6-year-old sister who likes to do her thing. It will take a bit for her to warm up to you. Most important is the puppy. We have a huge fenced in yard for nice days. They can be out playing for hours at a time. Also will have some walks to do. At this time it will be Wednesdays only. Schedules may vary and more hours may be needed. Both dogs are 8 pounds each.
