My first doxie was a neighborhood drop off. She was 5, pregnant, and every worm in the book including heartworm. I named her Saucie, short for Sausage dog. (Original, are we?) Had her 10 years after that. Vet refused to treat her heartworm due to size and age. She dies of cancer before the heartworm. My current doxie is solid dark chocolate colored and named, what else, Cocoa. LOL
