Skin ulcerations with pus are a common dermatological issue in dogs, especially in hot and humid climates like Vietnam. This condition not only affects your pet's appearance but also causes discomfort. Here’s an in-depth look at what this condition entails and how to treat it effectively.
1. What is Skin Ulceration with Pus in Dogs?
Skin ulceration with pus in dogs refers to a severe skin infection characterized by inflammation and pus formation. This condition is typically classified based on the depth and extent of the skin lesions. It involves the formation of pustules within the epidermis or hair follicles. In deep skin infections, the infection spreads from the hair follicles to the surrounding skin tissue.
2. Causes of Skin Ulceration with Pus
The primary cause of skin ulceration with pus is bacterial infection, particularly by Staphylococcus pseudintermedius. This gram-positive bacterium is a common pathogen in dogs. Other direct causes include:
- Flea, tick, or parasite bites
- Skin trauma or burns
- Fungal infections
- Bacterial or viral infections
- Nutritional deficiencies
- Cancers such as lymphoma or basal cell carcinoma
- Parasite infestations
- Autoimmune disorders
- Congenital anomalies
- Metabolic disorders
3. Symptoms of Skin Ulceration with Pus
Dogs with skin ulceration and pus often show symptoms on their heads, hips, and sides of the chest. Long-haired dogs are more susceptible to developing pus-filled lesions compared to short-haired breeds. Symptoms include:
- Circular crusts on the skin
- Dry, flaky skin patches
- Hair loss in the affected area, with itching and pus formation
- Unpleasant odor
4. Treating Skin Ulceration with Pus at Home
To effectively treat this condition, it's crucial to identify the underlying cause and keep the affected area clean and dry. Antibiotic treatment is often necessary to combat the bacterial infection. Here’s a step-by-step guide to home treatment:
4.1. Initial Care
- Shave the hair around the infected area.
- Clean the area with an antiseptic solution.
- Use appropriate medication as needed. For mild cases, proper hygiene might suffice.
4.2. Medications for Treating Skin Ulceration with Pus 4.2.1. Injectable Medications
- Recommended products: Pharmectin, Bivermectin 0.1%, and Demodex.
- Dosage: Administer at least three injections, spaced 3-5 days apart, based on the dog's weight.
4.2.2. Oral Medications
- Recommended products: Nexgard and Bravecto.
- Dosage: Administer as you would dry food.
- Note: These medications are effective but can be expensive.
4.2.3. Topical Treatments
- Recommended products: Mitecyn or zinc oxide ointment.

5. Preventing Skin Ulceration and Pus in Dogs
5.1. Hygiene
- Maintain a clean living environment for your dog, and change bedding regularly to prevent skin infections.
5.2. Nutrition
- Provide a balanced diet to support overall health and immunity. Avoid overloading the liver and kidneys with high-protein foods to ensure effective detoxification and prevent skin issues.
5.3. Grooming
- Regularly trim and clean your dog’s coat. Long-haired breeds are prone to matted fur, which can lead to folliculitis and eventually skin ulcerations.
5.4. Parasite Control
- Regularly treat your dog for fleas, ticks, and other parasites to prevent their bites from causing infections and abscesses.
By following these guidelines, you can effectively manage and prevent skin ulceration and pus in dogs, ensuring your pet stays healthy and comfortable.
