I am so very sorry. I am thrilled that you had so much time with Courtney.
What you said "If there had not been a Courtney, there would not have been an adoption group, and a good many more houndies would have had a more difficult time finding their way to the couch." is so very true. I lost my first girl Scarlett almost 5 years ago, after 13.5 years together. Several greyhounds were adopted in NYC because of her. My walker met someone this weekend who had just adopted, and they knew about my Scarlett and my second girl Morgaine. Each of our hounds helps another one find a couch. That is their gift and blessing.
