Aww,
I know how you feel. I lost my Cocker in Oct of 2009. I think of my little Bailey a lot too, but I know that he's so much better off and not in pain anymore. I know this might sound strange to you,but I got my two Morkies soon after his passing. It really helped me heal faster. Not that I didn't miss or remember how much I loved my Bailey...it just brought the joy of having a happy healthy furbaby again. I also know that I'll see my Bailey again.
Have you thought about a new one yet?
