I'm so sorry for your loss. I just had to have my black cocker, Sarah, put to sleep last Wednesday. I too, am completely lost, and wonder if that ragged hole in my heart will ever heal. My Sarah was 14 and suffering from heart failure. I had known that the time would come when her life was over, but I guess I didn't realize how profound the grief would be. Like your dear Roscoe, Sarah's "doggyness" had been replaced with helplessness and suffering. I don't know what to say at this point; I only hope that time will dull this pain, so we can smile in the memories of our beloved pets.
