Pet Care Needed - Full-time / Part-time

Mordecai is a sweet little chiweeni. He is a people dog. My husband works from home but must go out of town sometimes two weeks at a time. When that happens I need someone to come in the middle of the day and take him out and play with him while I am at work. He wears a diaper (we rescued him and he just can't figure it out) He likes to come up to people not the other way around.
