Blog Loop In Footer on Every Page

I’m trying to figure out how to have a latest post blog loop on every page in my footer. This is my theme: https://lwebdesigns.net/blog/. How do you make a loop for the blog content on every page?

This is the code I am using:

Footer:

<div class="fourcolumn">
	<h2>Latest Post</h2>
	<?php if ( ! have_posts() ) : ?>
        <h1>Not Found</h1>
            <p>Apologies, but no results were found for the requested archive. Perhaps searching will help find a related post</p>
<?php endif; ?>  

<?php while ( have_posts() ) : the_post(); ?>  

       <div class="lp-dates"><?php the_time('M <br /> j') ?></div>

                <div class="latest-post"><a href="<?php the_permalink(); ?>"><?php wpe_excerpt('wpe_excerptlength_teaser', 'wpe_excerptmore'); ?></a><div class="dash-divider"></div></div>  

<?php endwhile; ?>
</div>

Functions:
`
<?php function wpe_excerptlength_teaser($length) {
return 8;
}
function wpe_excerptlength_index($length) {
return 30;
}
function wpe_excerptmore($more) {
return ‘…’;
} ?>
