There is no one definitive answer to this question as there are many factors that can contribute to whether or not a dog is a Dutch Shepherd. However, some general signs that a dog may be a Dutch Shepherd include being friendly and outgoing, being loyal and obedient, being intelligent and quick to learn, and being easy to train. Additionally, a dog's coat can be a good indicator of its breed, as some Dutch Shepherds are known to have a thick, soft coat that is easy to groom.
