Dogs come in all shapes, sizes, furs, and colors. You may see dogs with different eye colors and not think anything of it. The same goes for dogs with different tongue colors.

When spots on your dog’s tongue aren’t just color

Your dog’s black spots are usually nothing to worry about. Pigmentation is normal and offers just one more thing for you to love about your best friend. Thin of them as a birthmark or as freckles. That being said, it is a problem is if the spots change rapidly or if the texture is raised of different from the rest of the tongue. Canine oral cancers and melanomas can appear as raised spots or fleshy tumors. Another problem is if they are any color besides bluish black or they smell bad. Have your dog checked by a veterinarian if you see unusual changes in their mouth. Routine dental care, like brushing your dog’s teeth and oral examinations, is another thing you can do to help aid in early diagnosis or oral cancers.
