Pet Care Needed - Full-time / Part-time

I just moved to Colchester and I have a black lab. Shes a gentle soul but I think she is having some difficulty transitioning to a condo and a new place. She is barking (more like howling) during the day. I work at the hospital so I cant leave to check on her. I would like someone to stop by my house and take her for a walk and spend time with her. I think maybe late morning time? Early afternoon?
