Opening and closing active items
I strongly recommend refactoring your HTML. At the moment it works, and I have based a solution around your HTML, however I strongly recommend changing it into nested ul tags to make it easier to manipulate with jquery e.g. 

&lt;ul&gt;
  &lt;li&gt;Item a
    &lt;ul&gt;
      &lt;li&gt;Sub item&lt;/li&gt;
      &lt;li&gt;Another sub-item&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
&lt;/ul&gt;


That said:

I have removed display: none from your UL and am using JS to hide the nav divs on page load (this can be moved to the css, but this is just proof of concept).

The javascript has paired the class of the a tag to the class of the nav div in the path variable. 

When the user clicks on the nav link, all nav divs are hidden and the corresponding nav div for the clicked link is animated open.



var path = {
  'socialNav':'social_icons_list',
  'dogzNav':'dogz_list',
  'Nav':'navigation_list',
};

var navDivs = $('.social_icons_list,.dogz_list,.navigation_list');

$(document).on('ready', function(){
  navDivs.hide();
  $('a.socialNav, a.dogzNav, a.Nav').on('click', function(){
    navDivs.hide();
    navDivs.filter('.' + path[$(this).attr('class')]).slideDown(500);
  });
});
