Other Reason

White spots on dog’s tongue can occur due to a number of less common causes. They are mostly not dangerous.

  1. Papillomas. Appear because of the virus and rarely degenerate into cancer. They initially look like small white spots, which after a considerable period of time can become dark. Papillomas do not rise above the surrounding tissues and do not interfere with the animal. The large size of such formations is a rare phenomenon. The development of such spots, which can be not only in the tongue, but also in the palate and lips, begins at the time of the fall of immunity, when the virus is not constrained by the natural defenses of the body. After the restoration of the immune system spot-papillomas often disappear on their own. If they are very large and bring discomfort to the dog, surgical excision should be carried out.
  2. Traces of injuries. If the dog’s tongue was burned or seriously injured, then a dark spot often appear at the injured place, which is a scar with intense pigmentation. Its color is usually brown, but can be black. Such spots, if you touch them, are denser than the tongue. The dog does not feel discomfort when touching the spots. Gradually over time, these scars become lighter, and sometimes completely disappear. They do not need to be treated, as they are a natural process of tissue healing.
  3. Malocclusion. A similar phenomenon often occurs in dogs with a shortened upper jaw, when due to the features of its structure, the teeth of the animal permanently affect the tongue. This leads to its local irritation, and due to friction begins pigmentation change. Brownish spots occur. They do not differ by touch from the surrounding tissues and do not change with age. Spots are formed soon after the change of teeth and remain until age tooth loss of the dog.

Black spots on the tongue of the dog are not a pathology and do not threaten the life of the pet, so the owners should calmly respond to their appearance.
