What about training him to do a few low-key tricks that he doesn't already know? Things like shake, roll over, play dead, speak, spin, pick it up, etc? That will help keep him mentally stimulated.

I play a lot of 'games' -

Hiding treats/kibble in one hand and having him correctly 'paw' the correct hand before he gets to eat it

I hide things in other rooms that he has to find. I show him prior to hiding it, he isn't allowed to watch, then he goes to find it. He's walking around but we mostly do it indoors and he's searching so not fully running around but just meandering and looking and sniffing.

Food/treat puzzles are one of the best ideas, imo.


Kongs

snuffle mat/ball (for the ball use a Hol-ee Roller toy
and it's the same premise - tie a bunch of fabric to it and insert the treat or toy inside; bonus points for using various styles of fabric to stimulate his senses - jeans/shirts/flannel/etc)

Take a clean empty plastic bottle or jug and put treats in it and teach him to roll it around so they fall out.

Kong Wobbler is fun but can get crazy with my pup so maybe contain him in a smaller room or save that until he's further in recovery

Presents - I put a treat in a thin cardboard box (Granola bar/cereal/Jello/etc) and tape the heck out of it. Sometimes when I'm especially looking forward to cleaning his mess(/s) I'll wrap in wrapping paper, too. Small boxes go inside the snuffle ball or inside another, bigger box. I hide it around the house/room or just give it to him and he shreds it into cardboard confetti to get to the treat. My dog is closely monitored and doesn't eat paper or shred anything unless it's specifically given to him for that purpose so disregard if your dog tends to destroy other stuff.

The Hol-ee Roller toy on its own is fantastic, too. I keep it as a snuffle ball nearly always and put things in there that he has to work to get out - things like these Dinosaur Chews, DreamBone Bones, dental chews, other toys like a small plushy or squeaker mat animal, etc. It's probably the greatest toy of all time for us and my dog has surprisingly not destroyed it considering how often he plays with it.



I make my own cheap versions of a lot of the puzzle toys I see on amazon like the ones from Outward Hound or Nina Ottosson. Nothing cute to look at but my dog loves em. It's partly how I trained him - while playing I would just repeat what he was doing - pull, pick it up, push, use your hands/nose, etc.

Long(er) lasting chews - bully sticks, cows ears, etc. I give mine Himalayan chews and some other harder ones but some vets discourage this so ymmv.

If he's not on dietary restrictions you could offer treats that are a bit more 'exotic' than what he usually gets - kangaroo, alligator, buffalo, etc. There's mental stimulation in discovering new things and getting special treats. I make mine do certain tasks before he gets any meal/treat/walk/etc - sit, sit pretty, shake, high five, etc.

I'm a little crazy and have a lot of time on my hands so I'm always doing something with my pupper. These are the ideas that work best when I'm not feeling well enough for another walk or need him to be quiet while I work on something or whatever.
