Should I worry about black spots on my puppy's gums while teething?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 6 months and 2 days old | 6 lbs

Puppy has symmetrical black spots on his gums on the inside of his upper pre molars. is this because he’s losing those teeth now? He’s lost his incisors and lower k-9’s so far, as far as I know

Its not normal for the gums to become pigmented from losing teeth but if you are seeing it on both sides, I would not be suspicious of anything abnormal. Monitor for any signs of abscesses from the puppy teeth-usually this will look like a red bump. I hope this helps with little Buster!

    That depends. Many dogs naturally have areas of black gums. If however this is a new development or if you see other signs of disease, it could indicate a tooth infection or melanoma (a cancer). I recommend to play it safe and have Zoe examined since a physical exam is the best way to determine if this is pathological. I hope this helps.

    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.
