Cephalexin for dogs is a broad-spectrum antibiotic commonly used to treat bacterial infections in dogs. It belongs to the cephalosporin class, which works by inhibiting the growth of bacteria, making it effective against a wide range of infections, including skin, urinary tract, respiratory, and bone infections. Cephalexin is often prescribed for its effectiveness, safety, and minimal side effects. However, it's essential to follow your veterinarian's dosage and treatment plan closely to ensure the best outcome for your pet. Never administer cephalexin without veterinary guidance, as improper use can lead to resistance or adverse reactions in your dog.
