I cannot even imagine such a loss. Please know that Binky loved you and lived a full life, although you may be sad, Binky is out of pain and lived a full happy life.
I recommend the book called, "A Dog's Purpose" for anyone who's ever loved (like all of us) or lost a dog, its a fiction novel from a dog's perspective and sheds light on how they feel about their owners and their lives. One of the BEST books I've ever read.
Reading that book will definitely heal you to some extent. I'm sorry again, but it's better to have loved and lost, then to have never loved at all
