Sorry to hear of your loss. We lost our Barley last September and were devastated, so I know what you must be going through. I found writing on COL helped me, there are so many lovely people out there and most know exactly what you are experiencing.
I have found two rescue dogs through Dogpagesforum. The gorgeous Cagney, posted as an orange roan cocker cross, but isn't, (he may be a Brittany Spaniel, or, possibly a SpringerXRetriever) came to us in November and last weekend we picked up the dashing Charlie, a 2 and 1/2 year old blue roan cocker. What a joy to have a cocker back in our home.
My advice to you is never give up hope, keep looking, every day if possible and believe in fate, if it's meant to be it will happen. I never thought I stood a chance with Charlie, but like a jigsaw, it all fell into place. The same with Cagney, I was pipped at the post, then a phonecall out of the blue and he was mine.
Good luck with your search, I am sure you will find your forever friend soon.
