mydeafdog.com lost some Google pagerank in this Aprils update back down to PR1

i think know why cos i have changed a lot of the keywords and changed Wordpress backend stuff. Plus i really haven't spent as much time on her as i should have been...

Anyways i want to do a full redesign on the site, remove the blog and add a custom made website to concentrate on the discount coupon codes that are doing quite well..... hopefully this site redesign can be done by the end...
