You can use query scopes http://laravel.com/docs/eloquent#query-scopes to make it verbose and easier in your controller (or wherever you will be doing it in future) then chain them according to your needs:

// Dog model
public function scopeSearchBreed($query, $breed)
{
  $query->whereHas('breed', function ($q) use ($breed) {
    $q->where('name', 'like', "%{$breed}%");
  });
}

public function scopeWithinRadius($query, $radius)
{
  $query->where(...); // do math here
}

Then all you need is this:

public function index()
{
  $q = Dog::query();

  if (Input::has('search'))
  {
     // simple where here or another scope, whatever you like
     $q->where('name','like',Input::get('search'));
  }

  if (Input::has('search-breed'))
  {
     $q->searchBreed(Input::get('search-breed'));
  }

  if (Input::has('sex'))
  {
     $q->where('sex', Input::get('sex'));
  }

  if (Input::has('radius'))
  {
     $q->withinRadius(Input::get('radius'));
  }

  $dogs = $q->orderBy(..)->paginate(5);
