Bacterial infections in dogs are commonly treated with antibiotics, with cephalexin for dogs being a widely prescribed option. Cephalexin, a first-generation cephalosporin, effectively targets skin, urinary tract, and soft tissue infections caused by bacteria like Staphylococcus. Administered orally, dosages typically range from 10-15 mg/kg every 8-12 hours, depending on the infection’s severity. Other treatments include amoxicillin-clavulanate for broader coverage or enrofloxacin for resistant strains. Always consult a veterinarian for accurate diagnosis and dosing, as misuse can lead to resistance. Supportive care, like hydration and wound management, enhances recovery. Regular monitoring ensures treatment success and minimizes side effects.
