Why does a dog's tongue turn white?

Under normal circumstances, a dog's tongue should be a rainbow color. However, if it suddenly turns white, it must mean that there is something abnormal in the dog's body. Some people say that white tongue in dogs is mostly caused by gastrointestinal diseases. For example, eating some food that is not easy to digest, drinking a lot of milk, etc. Due to gastrointestinal diseases and other diseases, dogs' tongues have problems and become very white.
In addition, anemia, heart disease, etc. can also cause white tongue in dogs. Of course, in addition to this symptom, dogs with anemia or heart disease will also show other symptoms. Generally speaking, it is uncommon for dogs to have white tongues. They usually occur in the stage of severe anemia (yellow tongues in dogs suffering from infectious hepatitis).

What should I do if my dog’s tongue turns white?

It is not a trivial matter for a dog to have a white tongue. It is best to send the dog to a professional pet hospital for a thorough examination to ensure the dog's physical health. If the dog is sick, it should be treated in time so that the pet dog can recover as soon as possible.
