Strangles in Puppies: Vet’s 2025 Guide to Juvenile Cellulitis 🐶🩺
By Dr Duncan Houston, BVSc – Ask A Vet Blog
🔍 What is Puppy Strangles?
Strangles, also known as juvenile cellulitis or sterile granulomatous dermatitis and lymphadenitis, is a rare but dramatic skin condition in puppies. It typically appears between 3 weeks and 6 months of age and can be mistaken for an insect bite or severe allergic reaction due to facial swelling 🐾.
The puppy’s face, muzzle, eyelids, and lips swell rapidly, followed by inflammation of the lymph nodes in the neck. Pimples, crusting, and bleeding lesions may follow. This condition is painful—not itchy—and requires urgent medical care ⚠️.
🧬 What Causes Strangles?
Strangles is an immune-mediated disease. The puppy’s own immune system overreacts and begins attacking skin tissues and lymph nodes. There is no known external cause, and the condition is not contagious 🧪.
Secondary bacterial infections often occur due to broken skin, but they are not the root problem. The core issue is immune dysfunction, and treatment must focus on suppressing this overactivity 🧠.
🐶 Breeds at Higher Risk
Certain breeds seem predisposed to developing strangles:
- Golden Retrievers 🌟
- Dachshunds 🐾
- Gordon Setters 🐕
However, any breed can be affected. The disease may occur suddenly, even in previously healthy pups.
⚠️ Symptoms to Watch
Strangles often begins with subtle facial swelling and rapidly progresses over hours to days. Common signs include:
- 💨 Facial and muzzle swelling (sometimes severe)
- 👁️ Puffy or crusted eyelids
- 🧼 Crusting pustules around the lips, nose, and face
- 🔴 Swollen lymph nodes (under the jaw/neck)
- 🥱 Lethargy, fever, joint swelling (25% of cases)
- 🍽️ Loss of appetite
Lesions may also appear on the inner ear flaps or in scattered patches elsewhere on the body.
🔬 How is It Diagnosed?
Puppy strangles has a distinctive appearance, and veterinarians can often diagnose it based on clinical signs. However, it’s critical to rule out other conditions before initiating immune-suppressive treatment 🧪:
Tests May Include:
- Skin scraping: To rule out demodectic mange
- Cytology: To evaluate pustule contents under the microscope
- Skin biopsy: For unclear or severe cases
In strangles, cytology typically shows abundant inflammatory cells but no bacteria, indicating sterile inflammation.
💊 Treatment Plan
The cornerstone of treatment is high-dose corticosteroids to suppress the inappropriate immune response. Early and aggressive treatment greatly improves outcomes and reduces the risk of scarring 🛡️.
1. Corticosteroids
- Prednisone: Main drug of choice
- Rapid improvement usually within 2–3 days
- Dose tapering over 2–4 weeks
2. Antibiotics
- Used only for secondary infections
- Selected based on cytology or skin culture
3. Pain Management
- NSAIDs are not recommended with steroids due to GI risk
- Pain is controlled primarily through inflammation reduction
📅 Recovery Outlook
With proper treatment, most puppies recover fully in 10 to 14 days. Scarring or permanent hair loss may occur in severe cases or if treatment is delayed. Relapse is rare 🌟.
🩺 Home Care Tips
- 📅 Complete the full course of medication—even if signs improve early
- 🧼 Keep skin lesions clean and dry
- 🧴 Apply topical antibiotic ointments if advised
- 🧤 Use an e-collar to prevent scratching or licking
🚫 Avoid Delays
Delaying corticosteroid treatment can lead to:
- Permanent alopecia (hair loss)
- Extensive facial scarring
- Systemic illness or risk of death (in severe cases)
