The sounds in the veterinarian’s office come alive. A Schnauzer puppy whimpers in the lap of a young woman. A European shorthair hisses from a soft-sided carrier. I’ve been in a lot of pain lately—but my human family needs me—so I put on a brave face and wagged my tail one last time. The entire pack is here with me today. The little one, Jenny, gives me a long hug, and I feel tiny tears fall on the back of my neck. The needle prick burns my leg momentarily before I fall asleep, staring into Jenny’s loving eyes.
