I am so glad he had a nice visit, and is in a facility where his care can be met with the appropriate level of staffing. Are you allowed to bring any of the fluffs with you on visits as "therapy dogs?"

One thing that seemed to help with Aunt Bertha, who near the end had no short-term memory to speak of, was to bring her flowers when I visited, so there'd be evidence that "someone" had been there recently once I left. It also meant more people visited her room, which was a nice benefit! I was fortunate in that she always recognized me, she wasn't diagnosed with any particular dementia, but this was about 15 years ago now, it was just like all her systems were slowly shutting down as she aged. She was in her nineties.
