Im pretty sure that the answer is C
When I was 13 I had a dog as a birthday present it was a girl and we named her coco. She went everywhere with me we did everything together by the time I was 16 she was old and slowed down and we thought that was from old age. Coco had brain cancer we didn’t know what to do and we went to every vet in our state but nothing was helping. Coco pushed in for another two years till she passed.
I was so upset and devastated that I didn’t want another pet again but I got another dog a Great Dane named Sham rock he’d love coco they would fit in perfectly. Sham rock was the dog that brought me to love animals again and why I’m think about being a veterinarian when I grow up.
