Strep Throat in Dogs: Symptoms, Causes, and Treatment Options

Yes, dogs can develop streptococcal pharyngitis ("strep throat"), though it is less common than in humans.

Cause

Primarily Streptococcus pyogenes (Group A Strep), the same species that infects humans. However, canine strains are often distinct, and cross-species transmission is rare.

Symptoms

• Sore throat, difficulty swallowing
• Fever, lethargy
• Loss of appetite
• Enlarged tonsils/lymph nodes
• Coughing, gagging

Signs may be mild or subclinical.

Diagnosis & Treatment

• Throat culture or PCR confirms S. pyogenes
• Antibiotics: Penicillin or amoxicillin (first-line); alternatives for allergies
• Supportive care: Soft food, hydration, rest
• Isolate from other dogs during treatment

Recurrent or severe cases warrant investigation for underlying immunosuppression or carrier status. Good hygiene reduces environmental contamination.
