});

Breadcrumbs::register('app.retailer.index', function ($breadcrumbs) {

    $breadcrumbs->push($retailer->name, route('app.retailer.show', $retailer->slug));

    $breadcrumbs->parent('app.retailer.show');
    $breadcrumbs->push('Utilizadores', route('app.retailer.users.index', $retailer->slug));
});

Model binding:

        $router->bind('retailer', function ($value) {
            return Retailer::whereSlug($value)->first();
        });

You're missing the $retailer parameter in this line:

$breadcrumbs->parent('app.retailer.show');
