German Shepherds are one of the most popular pet dogs in the world. In fact, they rank among the top three of America’s most favorite. They are strong, agile, well-muscled, and have a very good appearance. They are also an obedient and loyal breed and are easy to train. There are many factors to consider in choosing a German Shepherd. The more general factors are appearance, health, strength, and intelligence. One great factor is also the gender. The gender of which dog to choose is, of course, strictly a matter of preference. But you would want to know if there is a big difference between the male and female in their appearance, behavior or abilities. You may want to choose a female German Shepherd, for example, for their comparably more genteel manner or simply for the reason that they are able to give birth to pups.
