However, there can be some natural variation depending on the breed and individual dog. Some dogs might have slightly darker or more pigmented tongues, even with a healthy pink base.
Here are some things to keep in mind:
* Black tongues: Some breeds, like Chow Chows and Shar-Peis, are known to have black tongues. This is perfectly normal for these breeds.
* Spotted tongues: Some dogs might have spots or patches of darker pigmentation on their tongues. This is also usually harmless.
* Red or swollen tongue: If your dog's tongue appears red, swollen, or has any sores or lesions, it could be a sign of an underlying medical condition. Consult your veterinarian immediately.
It's always best to consult your vet if you have any concerns about your dog's tongue.
