HOW to do bold possessive nouns?

To make possessive nouns bold, you first write the noun in its possessive form by adding an apostrophe and an "s" (e.g., "the dog's bone"). Then, to bold the text, you can use formatting options depending on the platform: for example, in Markdown, you would use double asterisks or double underscores (e.g., dog's or dog's). In Word processors, you can typically highlight the text and press the bold button or use the keyboard shortcut (Ctrl+B or Command+B).
