What's wrong with a dog having a small black spot? This may be due to toxic substances that the dog has been exposed to, or itching caused by the dog's skin being exposed to pollen or other dust, causing the dog to bite its own skin, thus forming small black spots. To determine the cause of the small black spot, it is recommended to take the dog to the veterinarian to determine the cause of the symptoms and take appropriate treatment measures.
1. Pigmentation
Some dogs will experience pigmentation as they grow older, which is usually called age spots or age spots. It is a natural phenomenon that occurs as the dog grows older. It usually appears on the abdomen, elbows, around the mouth and nose, around the eyes, etc., and is round or irregular in shape, with varying colors and shades of colors. Although it looks a bit strange, it does not pose a threat to the health of the dog, so the owner does not have to worry too much.
2. Folliculitis
If the dog consumes too greasy food for a long time, does not take a bath for a long time, or does not secrete hormones, it will cause damage to the hair follicles, resulting in folliculitis, and black spots on the body, and it will also be accompanied by symptoms such as hair loss and redness and swelling of the skin. If not treated in time, folliculitis will further develop and severe pyoderma will form, so it is recommended that the owner consult a pet doctor in time for medication treatment.
3. Eutectic parasite infection
If the owner has not helped the dog with external deworming for a long time, it is easy to be infected with ectoparasitics such as fleas and lice. These parasites lay eggs in dogs' hair and discharge feces, which are in the form of small black residue. In this regard, the owner can put these small black residue into the water. If blood-colored spots are found, it means that fleas or lice may exist on the dog. At this time, the owner needs to perform external deworming on the dog in time.
4. Skin diseases
Some bacterial and fungal infections may also cause small black spots to appear on dogs. In this case, the dog's skin will usually become red, itchy, and the hair around the small black spots may fall off. If the dog is found to have the above symptoms, it is recommended that the owner take the dog to the pet hospital for examination in time, and then treat it according to the examination results.
