Home Health Aide Needed

I need a senior care provider with experience with someone with short term memory issues. Job responsibilities would include providing companionship/conversation, heating a prepared lunch or snack in the microwave , and doing a 2 minute bathroom walk in the back yard with a geriatric friendly Labrador retriever. We're looking for someone who is outgoing and friendly, and willing to engage, and likes dogs. We need someone weekends only for about 4-5 hours each day during the afternoon.
