Think of breeds of dogs that do not have spots. For example, Labrador Retrievers, Rottweilers, and German Shepherds are commonly known breeds that do not generally possess spots on their bodies.
04
Verify the Counterexample
Ensure that the chosen dog breed indeed lacks spots. Look at images, breed descriptions, or refer to knowledge about dogs confirming that the chosen breed, such as a Labrador Retriever, typically has a single coat color without spots.
