title: Regex Ignore Proceeding Words
body: <p>I am trying to create a regex expression that starts with a certain word and ignores any other same proceeding words. </p>
  
  <p>For example, if my string starts with the word "dog" and ends with "fish", how do I ignore any proceeding "dog" words and only match the last one?</p>
  
  <p><strong>dog cat fish</strong></p>
  
  <p><strike>dog</strike> <strong>dog cat fish</strong> &lt;- ignore first word "dog" and match second "dog" word. </p>
  
  <p><strike>dog</strike> <strike>dog</strike> <strong>dog cat fish</strong> &lt;- ignore first and second "dog" words and match third "dog" word.</p>
