Just made pork shoulder in slow cooker for pulled pork. Should I save the bone for stock?

I am not sure if it is worth the trouble unless you are going to use it soon and roll it over into another recipe.

Personally, I wouldn't bother. It won't have any of the highly prized collagen-rich cartilage

There might be a wee bit of flavor left, but I don't care to operate my freezer as a junkyard with marginally useful leftovers like this.

But that's just me...

Even if the bone was cooked with the pork, I would save it. Any broth or stock you make with it will be light, but toss a few pork neck bones in there and you have the great beginnings of a ramen soup or Pho. There is an amazing soup on this site that you start by making a pork stock. It takes 3 days to make it, but easy stuff and it's well worth the wait. I'll come back and link it after I get home to my tablet. I think it's by Gingerroot and has the word fusion in it, but don't completely trust my memory.

At this point, there's not much flavor left in the bone. If you know a dog, this is a happy gift for them!
