What is the black spot on the dog's tongue?

Causes of dark spots on a dog's tongue:

1. The black spot on the dog’s tongue is caused by melanin deposition, which is mostly congenital inheritance. If it does not affect the dog’s spiritual appetite, you don’t have to worry about it deliberately.

2. If the dog's tongue is stabbed by a sharp object while eating, causing blood stasis, it will also cause black spots on the dog's tongue.

3. Oral diseases may cause black spots on the tongue.

4. Black spots on the tongue of some dogs may also be birthmarks.

5. Caused by the use of drugs, for example, the use of broad-spectrum antibiotics leads to abnormal deposition of pigment on the dog’s tongue and black coating.

Common oral diseases in dogs:

1. Dental calculus: Dental calculus is mainly composed of food residues and bacteria, which is the culprit of bad breath and periodontal disease. Once dental calculus forms on a dog’s teeth, it is difficult to remove.

2. Gingivitis: Gingivitis is the precursor of periodontal disease, and it mostly occurs at the junction of gums and teeth, which is also called gingival sulcus.

3. Periodontitis: Periodontitis involves acute or chronic inflammation of the gums and alveolar bone tissue around the teeth. If left untreated, it can lead to receding gums and loose teeth.

4. Tooth decay: Accumulation of food residues in the mouth and unbalanced nutrition will cause tooth decay. Tooth decay can cause gum pain, tooth necrosis and loss of appetite in dogs.

5. Irregular bite: First, there is a problem in the development of the upper and lower jaws, which leads to the inability to open and close normally. The second is that when the permanent teeth erupt, they are held by the temporary teeth, resulting in ectopic growth. In dogs with malocclusion, the teeth will get stuck when closing the mouth, which will affect eating.

6. Broken teeth: Dogs are naturally fond of gnawing, and their teeth will be worn or even broken during the process of gnawing and chewing hard things.

7. Dental plaque: If the parents have never cared for the dog’s teeth, there may be plaque on the dog’s teeth caused by food residues and bacteria.
