Thanks for snippet but you use ext as constant it should be string:

<?php

    $url = wp_get_attachment_url( get_post_thumbnail_id() );
    $filetype = wp_check_filetype($url);

    if ($filetype['ext'] == 'gif')
    
    {the_post_thumbnail('full', array('class' => 'img-responsive')); }

    else
    {the_post_thumbnail('medium', array('class' => 'img-responsive'));}

?>
