There are liver spotted dalmatians(brown spotted).....thats normal...the nose might change to a brown in the future.
You got yourself a liver-spotted Dalmatian, and don't worry. This is just another type. There are two types of Dalmatian breeds: black-spotted and liver-spotted. Black spotted Dals usually have deep brown eyes, black noses and of course, black spots. Liver-spotted dogs have brownish spots, amber eyes and a brown-looking nose. Dogs can have different color variations like caramel, lemon or blue. These colors are disapproved in showing dogs, along with blue eyes, incomplete eye rings, and patches (solid black).
