Carrupes are a common skin disease in dogs. The causes of warts in dogs include poor immunity, irregular lifestyle, endocrine disorders, etc. If your dog gets warts, you need to go to the pet hospital for examination to see if there are any lesions or inflammation. If it is a malignant tumor, it needs to be surgically removed as soon as possible. If it is benign, it does not need to be removed. Pay more attention to observation at ordinary times, and seek medical attention if you find any abnormalities.
