While a dog bite appears to be straightforward, it’s important to understand the legal definition before proceeding with a dog bite case. A dog bite injury can be any wound caused when a dog’s mouth closes around a part of a person’s body. These wounds might tear into the skin, leaving behind deep cuts and gashes that require medical attention. However, the injury does not have to be visible to constitute a dog bite case. Some bites can cause internal injuries without even breaking the skin.
