Cephalexin is a first line drug of treating bacterial infections in dogs that are known to cause skin infections, wounds, and urinary tract complications. Being a cephalosporin antibiotic, it functions by preventing bacteria to construct cell walls, hence killing the vulnerable bacteria.
Take cephalexin only on prescription of a vet, as administration of antibiotics without a professional consultant may cause resistance and failure to treat.
