"On my first visit with McKenzie, a gentleman was calling, 'Help, help, help' from his room. And so my senior buddy who was with me said, 'I'm just going to go let the nurses know. It's probably OK.' And he motioned his hand for us to come closer and once he could touch her, he just immediately started petting her head, (he) calmed down. 'Hey puppy, pretty puppy. Don't leave me. Don't leave me. Stay with me,'" remembers Nicole Parks, who takes her Golden Retriever McKenzie on visits.
