What is what dog breed has black spots on roof of mouth?

The dog breed that typically has black spots on the roof of their mouth is the Dalmatian. This is due to a genetic trait that causes the melanin pigment to be expressed on specific parts of their body, including the roof of their mouth. Not all Dalmatians have black spots on their mouth, but it is a common characteristic. Other breeds may also have black spots on their mouth, but it is rarer and not as distinctive as in the Dalmatian breed.
