Causes of Dog Pyoderma

The main causes of dog pyoderma include allergic, autoimmune, endocrine, parasitic, human factors, and iatrogenic factors. If the living environment of the dog is poor, bathing is not timely, and the hygiene of the skin surface is poor, this type of disease is often more prevalent. The lesion sites are often focal, multifocal, or systemic, manifesting as papules, pustules, scales, and epidermal necrosis.

1. Allergic

Allergic pyoderma is mainly caused by skin allergies in dogs after being bitten by parasites. In addition, long-term exposure to allergens can also cause allergic pyoderma in dogs.

1. Autoimmune

If a dog's diet is monotonous or its immune system is abnormal, the skin's resistance to pathogenic bacteria in the external environment will decrease, and pyoderma may occur.

1. Endocrine

Hypothyroidism in dogs or excessive adrenaline secretion can affect skin function and trigger pyoderma.

1. Parasitic

This usually occurs when owners do not properly manage their dog's hygiene and parasite control, regularly clean their activity area, or give their dog regular baths. The most common causes are folliculitis and demodicosis.

1. Human factors

If a dog's living environment is damp and dirty, or if the dog is bathed too frequently, misuses drug baths, or over-brushes its fur, these human factors can easily damage the dog's normal skin structure. At this point, once the dog's skin is damaged, it is prone to bacterial infection and pyoderma.

1. Iatrogenic

Indiscriminate use of antibiotics and corticosteroids in dogs, or using drug baths without a doctor's advice, can lead to bacterial resistance on the dog's skin, reduce the dog's skin immunity, and increase the risk of pyoderma.
