What Causes Skin Discoloration in Dogs?

Skin discoloration refers to abnormal changes in skin color caused by skin lesions or pigmentation alterations.

Cause Investigation

1. Skin DiseasesSuch as demodicosis (caused by Demodex mites).
2. Genetic FactorsFor instance, inherent changes in melanin production.
3. Skin TumorsTumorous growths can lead to localized color shifts.
4. AgingAccumulation of melanin over time results in natural discoloration as dogs get older.

Solutions

1. If the skin gradually darkens without any signs of itching, licking, or hair loss, it is likely simple melanin deposition. This condition is harmless to the dog’s health and requires no intervention.
2. If discoloration is accompanied by itching or hair loss, it may indicate a skin disease. You can try applying pet-specific topical dermatological medication for a few days. Consult a veterinarian if there is no improvement.
3. If the discolored area swells into a lump, skin tumors should be suspected. Seek veterinary examination before taking any further action.

Prevention Measures

• Conduct regular external parasite prevention for your dog.
• Maintain consistent daily grooming and skin hygiene.
