Great pleasure if some one can help me to overcome this.Thank you.

I cant see any menu codes here. So provide us with adminhtml.xml if any.

However I will give you my random thoughts here. Your admin route is setup like this.

 <routers>
    <pets>
        <use>admin</use>
        <args>
            <module>Ffriends_Pets</module>
            <frontName>pets</frontName>
        </args>
    </pets>
</routers>

What this do is setuping an admin router for your module. It has no problem as of now. But this will leads all of your module's url (admin side) looks like this

  www.domain.com/pets/controller/method

But if you have a look on all of admin urls, it follows this convention

  www.domain.com/admin/controller/method

If you need the same effect, then you need to change your admin router setup like this.

<admin>
    <routers>
        <adminhtml>
            <args>
                <modules>
                    <ffriends_pets before="Mage_Adminhtml">Ffriends_Pets_Adminhtml</ffriends_pets >
                </modules>
            </args>
        </adminhtml>
    </routers>
</admin>

Second point comes in layout xml file. As per your current configuration, your layout xml file looks good. However if you adopt the method that I put forward, then there is slight change comes in layout xml file. Layout handle that you are currently using pets_adminhtml_pets_index will change to adminhtml_pets_index. This is because instead of pets router configuration now we are using adminhtml router configuration which is defined inside the core module Mage_Adminhtml.

Now as per the layout xml and configuration, there should be a controller present in your module. It would be

File : app/code/local/Ffriends/Pets/controllers/Adminhtml/PetsController.php

<?php
class Ffriends_Pets_Adminhtml_PetsController extends Mage_Adminhtml_Controller_Action
{
     public function indexAction()
     {
         $this->loadLayout();
         $this->renderLayout();
     }
}

Without this controller, nothing is going to show in admin side.

Side Note :- In order to have a custom menu, you need additional configurations. It will be normally do in adminhtml.xml file. There are plenty of tutorials available outside for set uping a menu. So google it.

1) Is web.xml being loaded?

To do so, create non-wellformed XML in the file by removing a closing tag and saving. When you reload a admin page you should see a simplexml parse error.
If you don't see the error, check
a) the layout cache is disabled,
b) the web.xml file system path and file name is correct c) the config cache has been refreshed or disabled

2) Is the block file loaded?

Check the var/log/exception.log file to see if there is a "Invalid Block Type" message in there.
If Magento is looking for a block with a class name Mage_Web_Block_Adminhtml_Grid, it means it can't resolve your block class group web/adminhtml_grid.
Add the global/blocks/web/class node to your config.xml file, with the node value Department_Web_Block.

If there is no error record in the exception.log file, add a die(__FILE__) statement outside of your class declaration to your block class. If Magento finds the file and includes it, you should see the file name as the only output when you try to reload the admin page.

3) Is your bock rendering something?

Does your block inherit the correct parent class? Depending on what you want to do it probably is one of

Mage_Adminhtml_Block_Widget_Grid_Container
Mage_Adminhtml_Block_Widget_Grid
Mage_Adminhtml_Block_Template
Mage_Adminhtml_Block_Abstract

Check a valid template file is assigned if you are extension one of the first three. If the template file doesn't exist, a page load will generate a message in the file var/log/system.log. If your block only extends the abstract block class, make sure that you implemented the _toHtml() method and that it returns a non-empty string.

The above steps should let you find the reason why Magento isn't showing what you expect.

Magento – Magento 1.9.2.3 isn’t finding Data helper in custom extension

After hours of fiddling and searching, I found the magic sauce in a comment thread on this SO post. I had to expand the comments to find it!

For posterity and in case you're banging your head on the same thing, here's the solution.

Check your logs (tail -f <magento_root>/var/log/system.log).

If you have copied any XML from the web, view it in a text editor and ensure that you do not have invisible characters!

Does not work:

<config>
    <menu>
        <namespace module="namespace_package">
            <title>Namespace</title>
            <sort_order>200</sort_order>
                <children>
                    <overview>
                    <title>Overview</title>
                    <sort_order>1</sort_order>
                    <action>adminhtml/namespace/index</action>
                </overview>
            </children>
        </namespace>
    </menu>
    <acl>
     <resources>
        <admin>
            <children>
                <namespace module="namespace_package">
                    <title>Top Level Namespace Menu Item</title>
                    <sort_order>1</sort_order>
                </namespace>
                </children>
            </admin>
        </resources>
    </acl>
</config>

Solution: make sure your module defined for the <config><menu> in adminhtml.xml is correctly using ONLY the namespace and not Namespace_Package or namespace_package.

This works:

<config>
    <menu>
        <namespace module="namespace">
            <title>Namespace</title>
            <sort_order>200</sort_order>
                <children>
                    <overview>
                    <title>Overview</title>
                    <sort_order>1</sort_order>
                    <action>adminhtml/namespace/index</action>
                </overview>
            </children>
        </namespace>
    </menu>
    <acl>
     <resources>
        <admin>
            <children>
                <namespace module="namespace">
                    <title>Top Level Namespace Menu Item</title>
                    <sort_order>1</sort_order>
                </namespace>
                </children>
            </admin>
        </resources>
    </acl>
</config>
