I'm sure you're right, Betty, that a dog like your Pinker needs a job or activities and ongoing training.
I agree with Kelly, too, about nose work being a good possible starting point.
Whole Dog Journal, IMO a very good print magazine for anyone with a dog, presents lots of suggestions here for owners of blind dogs
: https://www.whole-dog-journal.com/issues/7_4/features/Blind-Dogs_5622-1.html
They draw extensively from Caroline Levin's book
Living with Blind Dogs, which I think you already have, but there's a lot more here too.
They talk about using carpet runners as floor markers, placing one of those small tabletop fountains near the dog's water bowl as an audio alert, "showing" the dog when, for example, a piece of furniture is moved, and of course using essential oils (or even such baking extracts as vanilla and almond) to mark furniture edges, etc., or, using a different scent, to mark the way to the food dish, a doorway, and so on. (The essential oils were my first foray into special aids for a blind dog. I learned about this from an early edition of Levin's book and used the technique -- successfully -- for a blind dog I took care of while his owner was laid up with a lengthy illness.)
There are a few links to more resources at the bottom of the article.
Here's a page of activities for blind dogs
: https://wagwalking.com/activity/activities-for-small-blind-dogs
It's geared toward kids, I think, but it doesn't matter. (To get rid of the pop-up --- there's only one --- just click anywhere on the page outside the pop-up, and it'll disappear.)
Here's a blog about enrichment exercises
: https://barksfromtheguild.com/2018/04/09/encouraging-play-and-activity-with-newly-blind-dogs/
It has quite a few suggestions. One thing mentioned casually that I thought sounded good was
"Your dog may appreciate it if you wear a small bell or a set of keys on your belt loop when you are out for a walk so she can easily hear and keep track of you."
Here is an overview of helping a newly blind dog to adjust

Their comment about a newly blind dog perhaps withdrawing and ceasing to interact with his environment (under
Play Games) might be especially applicable.
This is pretty general

But the suggestion about a safe zone in #1, and also the one (#2) about speaking before touching the dog, both seemed like very good ideas.
("Make sure you have his attention before touching him so you don't scare or startle him.") Actually, all 17 seemed like really good reminders.
I was particularly looking for jobs/activities, Betty, and I'll keep checking out sites as I find them. (I was using
activities for newly blind dogs as search terms, but it turned out that activities info is pretty much mixed in with other helpful info.)
I'm thinking that other members too will find (or already know) some tips about activities for blind dogs.
