Are black spots on my dog's gums normal pigmentation or concerning?

Pet's info: Dog | Boston Terrier | Male | unneutered | 11 months and 24 days old | 18 lbs

I have a one year old Boston terrier. I noticed he has black spots in certain parts of his gun. His teeth look healthy. Is this normal pigmentation? Or is it something I should be worried about.

Hello. I noticed that your dog is quite young. It is very likely that these are just normal areas of pigmentation, but perhaps reposting with a photo would help us. Dark areas in the mouth that are concerning are usually raised, may have associated inflammation or odor. Many breeds of dogs have normal areas of pigment in the tongue or gums.
