Wow, a powerful story. This paragraph especially. Like an emotional
blow to my heart.

"All this time I was standing at the head of the table. I could see the moment that one fifty-three went from a curious puppy to a terrified puppy. He did not like being held down and he started to struggle. It was then that I finally found my voice. I bent over the struggling puppy and whispered, "Sam. Your name is Sam." At the sound of his name Sam quit struggling. He wagged his tail tentatively and his soft pink tongue darted out and licked my hand. And that is how he spent his last moment. I watched his eyes fade from hopefulness to nothingness. It was over very quickly. I had never even seen Peggy give the lethal shot. The tears could not be contained any longer. I kept my head down so as not to embarrass myself in front of the stoic Peggy. My tears fell onto the still body on the table. "Now you know," Peggy said softly. Then she turned away. "Ron will be waiting for you."
