Companion Care Needed - Full-time / Part-time

We are looking for a dependable, caring, and patient caregiver for our 90-year-old father on Saturdays from 9 a.m. to 8 p.m. He has dementia, uses a walker, and needs assistance getting to and from the bathroom, along with gentle reminders and guidance once he gets there. He also needs supervision and companionship. He lives with his 86-year-old wife, who is independent and does not require care. The caregiver will prepare and serve meals for both of them. We are looking for someone who is kind, attentive, comfortable with dementia care, and dependable. They have a friendly German Shepherd, so you must be comfortable around dogs.
