Perhaps what struck me so much about your story was the work you put into healing his heart. He gave it back in full. We cannot possibly ask more.
I might posit- and this for another time for you to consider- that while most of us who own, love and adore our fur babies, we all get that one which touches us in a remarkable way. Mine was a Blue Heeler named Buster, who died on the bumper of a truck when the dog sitter didn’t attend to the back door. I will never forgive myself for that oversight, but Buster is everpresent in my life. He was replaced with another Heeler, who grabbed my heart and held it tightly, once I allowed him to (and this is our work to do so) for the next eight years.
Our next pet needs permission to touch our hearts deeply. So take your time. Too soon means no room. Eddie will still fill you up completely. You’ll know when you’re ready, and you will feel the need for that warm weight against your back.
