Pet Cellulitis Symptom Guide | What to Watch For and When to Seek Care
Understand possible causes of Cellulitis and key home observations
Cellulitis is a deep bacterial infection of the skin and subcutaneous tissues. Check the lesion daily, record spread or worsening, and seek veterinary care promptly if it expands quickly or systemic changes occur.
What this symptom means clinically
Cellulitis occurs when bacteria enter the dermis and subcutaneous tissue through damaged skin or a penetrating wound, causing an acute inflammatory response. Local vasodilation, fluid leakage, and neutrophil infiltration lead to swelling, redness, warmth, and pain. Infection can spread through lymphatic channels or soft tissue and cause persistent inflammation.
🐱 In cats
In cats, cellulitis is often related to bite wounds or puncture injuries, allowing oral bacteria to cause deeper infection.
🐶 In dogs
In dogs, cellulitis often starts from penetrating trauma or skin breaks and commonly involves mixed bacterial infection with spreading subcutaneous inflammation.
