Why does my dog have a small white line on his gum? Is it serious?

I would recommend getting your vet to check this closely, it appears in the pictures that the lower canine is making contact with the gum and chronic irritation can cause inflammation, scarring and occasionally tumour changes

No it does not look anything to be worried about. It could be a lack of pigmentation of the scrotal skin. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

I'm wondering if you intended to attach a picture - if not, attaching a picture could help us determine what these might be. If they are flat they could be normal areas of pigment, and sometimes dogs will start to have more patches of pigment on their skin and mucous membranes as they age. If they look more red or purple bruising is possible which would be a concern - if you think this might be bruising you should see a vet right away since it could be a sign of a bleeding disorder. If they are raised then they could be oral growths or tumors and you should have a vet take a look.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. It looks like local gum pigmentation or mild inflammation. I don't think there is anything to worry about, but please show it to your vet the next time you take Tiny for an appointment.

Hi and thanks for your post! That black around the gum line is a normal pigment variation. This type of pigmenting of the gums can be normal in some dogs like the Siberian Huskies. It does not indicate a health concern. Thanks for using Petco Pet Education Center, formerly Petcoach!

This could be normal pigmentation in the gums. You can keep an eye on it now that your are brushing Snoopy's teeth daily. If it begins to grow or change rapidly, then he should be seen by your veterinarian.

White gums can be a sign of anemia or low red blood cells, dehydration, extreme pain or shock. While these conditions are serious, in general I would expect other signs as well. If Xena is her usual self I wouldn't be particularly concerned about her gum color. If she is lethargic, has a decreased appetite, or is vomiting or having diarrhea I'd recommend seeing a veterinarian if at all possible.
