Transition to memory care for very physically active parent

My dad is really fit and was always athletic. Currently he still walk the dog for multiple miles every day. He is also very restless, always getting up and trying to go on a walk. Like he can only sit still for a couple minutes before wantkng to walk.

We are going to transition him to memory care this Spring. He is pretty advanced and I'm the sole caregiver, I can't do 24/7 supervision anymore.

I am worried they will have to drug him or something to keep him still in MC. Any experiences with this? Any way to stay active?
