Dog bite wounds.

Dog bite wounds are a common problem with an infection rate only slightly higher than that for lacerations in general. Wounds may be sutured after debridement and thorough irrigation, unless they are located on the hand, where infection is common. Infection is caused by a variety of organisms. A penicillinase-resistant penicillin or cephalexin monohydrate is the drug of choice; studies suggest prophylactic antibiotic therapy may be useful, especially in high-risk wounds.
