He lives 75' from dad's house. He spends most days sitting in dad's livingroom watching TV. He eats dad's food or goes out to eat. He doesn't cook. He doesn't bathe or do laundry. His memory seems bad too. We have spoken to his son and told him that we (my sister in law and I) cannot care for his dad. If the son cannot get his dad to move should we call social services?
Yes, call social services and see if they can sort out this guy. If he doesn't help himself, who will? All the best.
