So what is the difference between male and female German Shepherd Dogs? I often hear people ask this when thinking about purchasing a puppy. They are unsure if they should consider a male or female. You sometimes hear opinions such as females are more aggressive, males are more stubborn, females are easier to train or males are more affectionate. In my experience, I have found that it really depends more on the individual dog and their personality. For every male vs. female theory, you can find just as many dogs that prove the opposite.
Genetics and pedigree can also play a role in how stubborn, easy to train or aggressive a dog may or may not be.
However, size is one characteristic that does normally hold true for each gender. In general, males are going to be larger than the females. Of course, there are always exceptions to the rule. There are some German Shepherds who end up larger or smaller, again depending on their genes and pedigree. Because of their size, males can be stronger and more difficult to physically handle if they are untrained. It is easier to hold the leash to a fifty-five-pound female than it is to hold the leash to an eighty-five-pound male. This is one reason why obedience training is very important when owning a German Shepherd Dog.
You also have the obvious gender differences. A female will come into heat if left intact. An intact male may become difficult to live with if there are females in heat nearby.
Basically, it comes down to a personal preference. If you are looking for a family pet, you are better off telling the breeder about your family and what you are looking for in a dog. The breeder can then match you with the puppy best suited for your home. If you already have one GSD and will be adding a second to your family, it is always best to go with the opposite sex. Same-sex aggression can sometimes be a problem in the German Shepherd breed.
