Looking For A Pet Sitter For 1 Dog In Mineola

I am just doing some research. My sister has a small dog. She has Alzheimer. They are both cared for at home right now but we are looking at assisted living options in Tyler and Mineola. most places don't offer services for dogs. She currently can feed him and let him out into her fenced yard. This wont be an option at assisted living. Would need him walked a couple times per day. Possibly fed too at some point as her disease progresses. The dog is about 12- 15 years old but in good health and is her only joy.
