Featured Image - Dashes or No Dashes in the space between words?

[Brickwood]

When inserting the Image Alt Text on a blog post Featured Image, what is the recommended method to appease our Google Overlords?  Dashes instead of spaces or just spaces?

Alt tags are designed to display a text description of an image if an image doesn't load, for those who cannot see the image, such as visually impaired readers or crawlers.

So regarding Google, I think the best practice is to use things the way they were meant to.

You can simply type as you would normally with spaces.

Alt tags do have a SEO significance, as do the image's file name. Both can be used to associate keywords or phrases with your web page, as well as the image search vertical.
