Black spots on a dog's body

Black spots on a dog's body may be caused by melanin deposition, skin diseases, or external parasite infections. First, if the dog has no other abnormalities, it may be a normal melanin deposition, and the owner doesn't need to worry too much. Secondly, if the dog has black spots along with symptoms such as skin redness, hair loss, itching, etc., it may be suffering from a skin disease or parasite infection, and it is necessary to take the dog to a pet hospital for inspection to determine the specific cause before treating it accordingly.

Melanin deposition

If a dog is often exposed to sunlight or subjected to ultraviolet radiation, it may cause black spots on the skin. In addition, as the dog ages, the skin will develop varying degrees of pigmentation with age, resulting in black spots. These are all normal phenomena, and as long as the dog has no other abnormalities, the owner doesn't need to be too nervous.

Skin diseases

If a dog contracts a fungal or bacterial infection, it can cause damage to the skin, which may result in black spots. It may also accompany symptoms such as skin redness, hair loss, dandruff, and itching. In this case, the owner needs to take the dog to a nearby pet hospital for inspection and treat the skin disease according to the type identified.

External parasite infections

If the owner hasn't given the dog a deworming treatment for a long time and the dog contracts fleas, the accumulation of flea feces may cause black spots. The owner can check by parting the dog's hair to see if there are any black granular substances. If so, take some and put them in water. If the water turns red, it indicates that the dog has fleas and needs to be treated with external deworming drugs containing non- praziquantel and selenium components.
