Grundlagen und mögliche Ursachen
A dog’s tongue is normally pink and moist. Changes in color and texture can indicate various problems. A white coating often occurs due to an accumulation of dead cells, bacteria, or fungi that settle on the surface of the tongue. Sometimes it is also the result of reduced saliva production, which hinders the natural cleaning of the tongue.
A common cause of a white coating can be a fungal infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease., especially by Candida fungi. These yeasts are normally present in small amounts in a dog’s mouth, but can multiply excessively if the immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites. It comprises a complex network of organs, cells, and molecules that work together to protect the body. is weakened. Such infections are often referred to as oralOral means "through the mouth" and refers to the intake of food, medication, or other substances through the mouth.

Certain systemic diseases, such as diabetes or kidney disease, can also be associated with changes in the tongue, as they affect the entire metabolism.
DehydrationDehydration occurs when the body loses more fluid than it takes in. This can lead to a number of problems, including headaches, Dizziness, and in extreme cases, renal failure or Cardiovascular collapse. is also a possible cause, as it reduces saliva production and leads to a dry mouth, which promotes the growth of microorganisms. In addition, nutrient deficiencies, especially a lack of certain vitamins and minerals, can lead to changes in the oralOral means "through the mouth" and refers to the intake of food, medication, or other substances through the mouth. In veterinary medicine, many treatments are administered orally. mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract. It serves to protect and facilitate the absorption of nutrients..
