What happens if a dog’s skin immunity is low?

Low skin immunity in dogs can lead to a range of health problems. First, the dog’s coat may become coarse, dull, and lackluster, and even show severe shedding. In addition, when the dog’s skin resistance is weak, it is usually more vulnerable to invasion by bacteria and viruses, triggering various skin diseases such as dermatitis and eczema. These diseases not only affect the dog’s appearance but may also cause discomfort such as itching and pain.
