Dog skin with black patches

Black patches on a dog's skin may be caused by fungal infections. In addition to the appearance of black patches, the dog may also be accompanied by symptoms such as itchy skin, redness, scaling, and so on. It is necessary to go to the pet hospital for inspection and treatment in a timely manner. Secondly, it may also be due to the excessive deposition of melanin in the dog's body, resulting in black patches. This is a normal phenomenon and the owner doesn't need to take excessive measures. Additionally, dogs with endocrine disorders such as hypothyroidism may also develop black spots.

Fungal infection

If a dog's skin is infected with fungi, it may develop black patches, along with symptoms such as itchy skin, redness, and scaling. In this case, the owner should immediately take the dog to a pet hospital for diagnosis and develop an appropriate anti-fungal treatment plan according to the type of fungus.

Pigment deposition

If the dog is older, the black spots may be age-related spots. As the dog ages, there will be varying degrees of pigment deposition on the skin, resulting in black spots. In addition, if the dog is often exposed to sunlight or subjected to ultraviolet radiation, it may also cause black spots in some areas. This is a normal situation and the owner doesn't need to be too worried. Natural bathing is sufficient.

Endocrine disorders

When a dog has an endocrine disorder, it may also develop black spots. For example, hypothyroidism can cause melanin deposition in the dog's skin. Symptoms may also include depression, lethargy, lack of exercise, extensive hair loss throughout the body, fear of cold, and weight gain. If the dog shows these symptoms, it is recommended to check the thyroid hormone level. If the thyroid hormone level is insufficient, supplementing thyroid hormone is advised.
