Black spots on a dog's tongue are natural. It's due to melanin, the same pigment that gives color to human skin.
Certain breeds like Chow Chows and Shar-Peis often have these spots. It's a unique characteristic in these dogs.
The spots are typically harmless. They don't cause pain, and they're not a sign of any health issue in most cases.
Black spots are often found on the tongue's lingual papillae. This is a natural variation in pigmentation.
The number of spots can increase with age and sun exposure. It's like a 'freckling' effect in some dogs.
Black spots don't require treatment. Your dog can live a perfectly healthy and happy life with these spots.
Don't worry about the spots indicating health problems. They're more of a cosmetic feature.
