If your dog has suppuration caused by bacterial infection, you need to use drugs containing neomycin and erythromycin. The owner needs to clean up the slough in the dog's ulcerated and purulent parts, and then use diluted hydrogen peroxide or iodophor for disinfection. Then apply antibacterial and anti-inflammatory drugs, as well as antiseptic and myogenic drugs for treatment. If it is severely rotted and smelly, it needs to be surgically removed.

Causes of dog skin suppuration:

1. Pyoderma caused by parasites, fungi, and bacterial infections. This situation is most likely due to the fact that it is not treated regularly. It is caused by good hygiene management and deworming work, not regularly cleaning its activity area, and not regularly bathing the dog.

2. Dogs suffer from allergic pyoderma due to long-term exposure to allergens.

3. Pyoderma caused by endocrine, metabolic or nutritional problems in dogs.

4. Hitting a sharp object, resulting in broken skin and suppuration.

5. There is a problem with diet, leading to suppuration.
