**Which option is best depends on the overall tone and content of your blog.** If your blog is geared towards pet owners who might be worried, option 2 or 3 might be a good choice. If it’s more informational and aimed at a general audience, option 1 or 4 might work. Choose the one that best reflects what kind of content you will create under this tag. You can usually insert these descriptions directly into the post_tag editor in your WordPress admin area, right under where you enter the tag name.
