An adult Siberian, on the other hand, may not be quite so cute, but may come with his or her manners. The decision between an adult and a puppy really should be made based on your situation. If you have ample time and patience, a puppy might be in order. But, if you work, are busy with young children, or otherwise occupied, perhaps an adult might be better. Each gender has its positives and negatives.
Males are larger than females, and if left intact tend to mark their territory.
Females, on the other hand, are smaller and if left unspayed will come into season twice a year. Both can make wonderful pets. The relative size may help you make your decision. If you already have a dog, its gender might help you make a decision about your Siberian. However, for the health of the dog, and for your peace of mind, if you are not going to show or breed your Siberian, have it spayed or neutered.
