The causes of canine pyoderma are mainly allergic, autoimmune, endocrine, parasitic, human factors and iatrogenic. If the dog's living environment is relatively poor, does not bathe on time, and the hygiene of the skin surface is relatively poor, then this type of disease is often more common. The lesions are mostly focal, multiple or systemic, manifesting as papules, pustules, dandruff, epidermal necrosis, etc.

1. Allergy

Allergy is mainly caused by pyoderma caused by skin allergies caused by dog ​​bites by parasites. In addition, if the dog is exposed to allergens for a long time, allergic pyoderma will also occur.

2. Autoimmunity

If the dog’s usual diet is relatively simple or its own immune system is abnormal, the skin’s resistance to pathogenic bacteria in the external environment will decrease. At this point, there is a high risk of contracting pyoderma.

3. Endocrine

Hypothyroidism or excessive secretion of adrenal hormones in dogs will affect the function of the skin and induce pyoderma.

4. Parasitism

This situation is usually caused by the owner not doing a good job in hygienic management and deworming of the dog, not regularly cleaning its activity area, and not regularly cleaning the dog's activity area. Caused by bathing the dog. The most common ones are pyoderma caused by hair follicles and scabies mites.

5. Human factors

If the dog’s living environment is humid and messy, or if the dog is bathed too frequently, uses medicated baths indiscriminately, or grooms the hair excessively, then these Human factors can easily destroy the normal structure of dog skin. At this time, once the dog's skin is damaged, it is easy to become infected with bacteria and cause pyoderma.

6. Iatrogenicity

If you blindly abuse antibiotics and cortisol drugs for dogs, or use medicated bath lotions for dogs without medical advice, it will cause dogs to suffer from iatrogenicity. Bacteria on the skin develop drug resistance, reducing the dog's skin's own immunity and increasing the risk of pyoderma.
