Cephalexin is commonly prescribed by veterinarians for treating bacterial skin infections in dogs. It is particularly effective against common pathogens such as Staphylococcus bacteria, which are often responsible for skin infections like pyoderma. Cephalexin works by disrupting the formation of the bacterial cell wall, leading to bacterial death. Veterinarians often prescribe it in oral form, and it’s generally well-tolerated by dogs, with few side effects. Dosage and duration depend on the severity of the infection, and it’s essential to follow the vet’s instructions to ensure the infection is fully treated and to prevent antibiotic resistance.
