Looking For A Pet Sitter For 1 Dog In Dallas

This is my 96-year-old mothers dog at her assisted living residence. Dexter the dog is about 18 pounds, and 11 years old. He needs to be walked 4 times a day, but my mother can only accomplish 2 walks. We need someone to walk him Monday through Sunday at 9:00 a.m. and around 6:00 p.m.
