Vet’s 2025 Guide to Canine Pyoderma Skin Infections & Treatment Tips
By Dr. Duncan Houston BVSc
What Is Pyoderma?
Canine pyoderma is a bacterial skin infection, typically caused by Staphylococcus pseudintermedius. It results in pustules, scabs, hair loss, redness, and itch. Severity ranges from superficial hot spots to deep nodules 🐕🔥
Types of Pyoderma
- Surface pyoderma: hot spots, intertrigo (skin fold infections) 🛁
- Superficial pyoderma: pustules, crusts, epidermal collarettes 📸
- Deep pyoderma: nodules, draining tracts, furunculosis 🩸
Signs & Symptoms
- Itchy red skin with pustules or scabs 🐾
- Odor, hair loss, oily skin or moist patches 🧴
- Recurrent ear infections or paw licking 🦻
- Hot spots that spread or deepen 📉
Diagnosis & Testing
- Skin cytology: for bacteria and inflammatory cells 🔬
- Cultures: for chronic or unresponsive infections 🧫
- Scrapings: rule out mange, ringworm, mites 🐛
- Bloodwork: if endocrine disease suspected (e.g., Cushing's) 🧪
Treatment
1. Topicals (First-line for mild cases)
- Medicated shampoos (chlorhexidine, miconazole) 🧼
- Antibacterial sprays, wipes, mousses 🧴
- Used 2–3 times weekly, adjust based on vet advice
2. Systemic Antibiotics (For deep or generalized cases)
- Cephalexin, clindamycin, or amoxicillin–clavulanate 💊
- Duration: 1 week beyond symptom resolution—typically 3–6 weeks ⏱️
- Always culture for recurrent or resistant infections 🔍
3. Address Root Cause
- Allergies (food, fleas, environmental) 🌾
- Hormonal imbalance (hypothyroidism, Cushing’s) ⚖️
- Immune suppression or skin barrier defects 🧬
Prognosis & Prevention
- Superficial pyoderma often resolves quickly with topicals ✅
- Deep cases need long-term care, may scar or recur 🧠
