Although there is not much difference between a male and a female German Shepherd, it is important to understand their specific traits before making your choice. Male German Shepherds are slightly more aggressive as compared to the females. If you are looking for a pet who is a great guard dog, you should purchase a male German Shepherd. On the other hand, if you are looking for a family pet that is gentle and loves spending time with your children, you should go for a female German Shepherd.
