Dementia Care Needed To Give Us A Evening Out

I need a companion care provider with Alzheimer's / Dementia experience for woman in her 80s. Duties include providing companionship and social interaction. Making sure she doesn't wander out of the house. Our 16-year-old daughter will be home, but she is fully self-sufficient. However, I don't want her trying to watch her grandmother. Must be a non-smoker, comfortable with dogs of all sizes, and have extensive experience with dementia care.
