Dog bites often cause a crushing-type wound because of their rounded teeth and strong jaws. The sharp pointed teeth of cats usually cause puncture wounds and lacerations that may inoculate bacteria into deep tissues. An adult dog can exert 200 pounds per square inch (psi) of pressure, with some large dogs able to exert 450 psi. Such extreme pressure may damage deeper structures, such as bones, blood vessels, tendons, muscle, and nerves.
