The term "Lab Mix" refers to a dog that is a cross between a Labrador Retriever and another breed. This can include any number of different breeds, but some common ones are Golden Retrievers, German Shepherds, or even other types of hunting dogs like the Chesapeake Bay Retriever. The result is often a mixed-breed dog that has characteristics from both parent breeds. These dogs can vary greatly in appearance and temperament depending on which two breeds they have been crossed with.
