This situation is mostly caused by skin diseases. Parents can take their dogs to the hospital for a skin examination to determine which skin disease the dog is infected with, and then provide targeted treatment. Skin diseases should also be prevented when raising dogs. In addition to keeping the dog's body dry, you should also take it out to bask in the sun and exercise more to increase its resistance.
Tip:
Many diseases in dogs are generally caused by decreased resistance. Parents should ensure that their dogs have adequate nutrition and strong enough resistance.
