Injuries -------- Most injuries to water turtles result from aggressive encounters with other turtles or household pets. Many water turtles are territorial, and fighting between them (especially between individuals of the same species) often results in serious wounds. Water turtles of widely varying sizes should not be housed together. Housing similarly sized turtles together helps reduce the number of injuries from fighting. Injuries may also occur during mating. Males may become overly aggressive during copulation and inflict bite wounds on the female. The male's rapid and sometimes premature withdrawal of an engorged penis also may injure the female's reproductive tract. Household pets, especially dogs, sometimes inflict serious wounds to the shells or soft tissues of water turtles. An injured turtle should be examined by an experienced veterinarian as soon as possible. Prompt attention to the wounds and early antibiotic therapy are vital to the favorable outcome of these cases. Usually, these injured turtles must be kept out of water or allowed only limited access to the water so that wound healing is not delayed. Veterinarians often employ epoxy resins or acrylic glues to repair shell injuries.
