Yes,cephalexin for dogs is effective for treating bacterial skin infections (pyoderma) in dogs. It is a broad-spectrum antibiotic that targets common bacteria such as Staphylococcus and Streptococcus, which often cause skin infections. Veterinarians commonly prescribe it for conditions like hot spots, abscesses, and wounds. Cephalexin works by inhibiting bacterial cell wall synthesis, leading to bacterial death. It is generally well-tolerated by dogs, though side effects like gastrointestinal upset may occur. Always follow your veterinarian’s instructions for dosage and treatment duration to ensure the infection is fully resolved and to prevent antibiotic resistance.
