My dog, Delilah, was 17 years old. She had a bright and loving Spirit, but her body was old and giving out on her. We had to make the decision to let her go. She was a Corgi/Sheltie mix. She was, without a doubt, the sweetest dog EVER.
I found this quote in a book by Dr. Charlene M. Proctor. It has helped me; maybe it will help someone else:
“My Pet knows that I am responsible for choosing the quality of its life. My love for this animal extends beyond any physical boundaries because love is forever. Therefore, my Pet and I exist forever. I trust that we will be together on the other side someday, and this parting is only temporary. I release this animal to the caretakers of its Spirit and trust that she is in a wonderful and peaceful place.”
