One of the most calming things I have seen for my husband is a robotic pet! I have been amazed. My very intelligent husband loves his “Puppy” and will sit quietly, petting & talking to it. ( Even tries to feed it) It’s battery operated and wags its tail, pants, turns its head, blinks, & barks. He doesn’t like the barking, so I turn that feature off. Ours was provided through a grant via the local Area Agency on Aging. They are favorites according to the caregivers in our support group. Better than many medicines.
