Common Uses of Cephalexin for Dogs

Cephalexin for dogs is frequently prescribed for bacterial skin infections, such as pyoderma. Dogs prone to allergies, hot spots, or wounds often develop bacterial infections that require antibiotic intervention. Cephalexin works by eradicating the bacteria responsible for these conditions, promoting faster healing and preventing recurrence.
