Work Step by Step
To link the word "Rover" to the URL http://animals.org/pets/dogs.html, you can modify the HTML document as follows:
```html
Example
My Pet Dog
My dog's name is Rover.
``` In the modified code, the `` tag is used to create a hyper link. The `href` attribute specifies the URL that the link should point to, in this case, "http://animals.org/pets/dogs.html". The text "Rover" is placed between the opening and closing `` tags, making it clickable and linked to the specified URL.
