I've had 2 rescue dogs over the years. In the 1970s it was a 1-eyed Collie-Husky puppy scheduled to be put down, as nobody wanted him. I sometimes had him wear an eye-patch, very cool-looking, and named him Patch, The One-Eyed Wonder Dog. He lived a full life to his teens.
My other rescue dog was a Cocker Spaniel puppy found abandoned in a field, along with his sibling. The shelter had already named them Andy & Sandy, with Sandy spoken-for before I arrived. Andy Dog was beautiful, but developed many health problems. I finally had to have him euthanized 6 years later at the vet, and watching him slip away while I petted and held him was very tough.
