Pustules on dogs may be caused by eczema, parasite infection, pyoderma, subcutaneous abscesses, etc. It is recommended that the owner take the dog to the pet hospital for examination first, remove the contents of the pustule, clean the wound, and disinfect the local area and apply medicine. If necessary, the dog should be injected with antibacterial and anti-inflammatory drugs or oral anti-inflammatory drugs at the same time. In addition, in order to avoid mixed infection in the affected area, it is generally necessary to shave the hair around the affected area of ​​the dog.

1. Eczema

If a dog lives in a cold and humid environment for a long time, it is easy to induce eczema, which is superficial pyoderma. It starts as a small red rash, which gradually develops into vesicles with pus. In severe cases, it may even ulcerate. Therefore, the owner must keep the dog’s living environment dry and warm. For local treatment, appropriate dosage forms of drugs can be selected according to the stage of the eczema, or medicated shampoo can be used for medicated baths. During treatment, the dog must be prevented from licking and biting the affected area. If yellow pustules appear on a large scale, they need to be taken to a pet hospital for treatment in time to avoid serious infection and aggravation of the condition.

2. Infection with parasites

If the owner does not deworm the dog on time, when the dog is infected with external parasites such as fleas and scabies mites, it will cause itching of the skin. Dogs scratch and bite frequently, which can lead to secondary infections and pus. At the same time, dogs will also experience symptoms such as skin redness and swelling, hair loss, and increased dandruff. If you find that your dog has these symptoms, you must consult a pet doctor in time to choose appropriate anthelmintics for your dog.

3. Suffering from pyoderma

Pyoderma is a skin disease mainly caused by purulent infection of the skin. It is mainly caused by bacterial infection. Shedding, skin redness, skin papules, scabs, and suppuration are all symptoms of pyoderma. If the dog is infected with pyoderma, it is recommended that the owner give the dog oral anti-inflammatory drugs containing amoxicillin and clavulanate potassium for treatment. At the same time, the affected area needs to be cleaned with normal saline and disinfected with dilute hydrogen peroxide or iodophor. .

4. Subcutaneous abscess

If the dog has recently received an injection, it may also cause a subcutaneous abscess in the dog due to incorrect injection posture. Because the appearance is consistent with that of a pustule, owners may confuse the two. If this is the case, the owner can use a hot towel to apply hot compress to the dog to reduce swelling, and if necessary, incision is needed.
