If you are considering adding two puppies to your home at the same time, you should seriously reconsider this option. There are many misconceptions and misunderstandings about this action and people sadly find out the hard way, which causes their family a lot of trouble and heartache.
The thought is that two puppies will keep each other busy, give each other exercise, etc… While this may be partially true, there are far more negatives than positives. Even the benefit of having them wear each other out will cause you problems in the long run. Many call this problem “littermate syndrome”.
Having one puppy in your home is a lot of work. It takes a lot of time, effort and work on your part to properly raise and train a German Shepherd Puppy. If you are unable to give that time and work, you should hold off on getting a puppy at this point. It is often hard for the average family to find the time and energy to properly raise one German Shepherd puppy properly. If you had two puppies at once, this is nearly impossible and both puppies (and your family) will suffer.
When you bring a puppy into your home, it is important that this puppy will bond with you (the owner and caregiver). If there is a second puppy in the picture, those puppies will bond to each other instead of you (the humans in your family). It is much more natural for two puppies to bond than for a puppy to bond to a human.
If your two puppies bond to each other, this will create many issues, not only with training but also just life in general. You will have a hard time getting and maintaining the attention of each puppy on you for training and socialization. Instead, they will want to play and pay attention to each other. This can cause separation anxiety between the two puppies if you try to take one somewhere without the other. This can also create difficulties with even basic obedience training. Without basic obedience training, your German Shepherd Dog can become a difficult and destructive pet.
Two puppies being raised together (whether they are littermates or just similar in age) can become so dependent on each other that they may begin to show fear and other issues with people. Their deep bond can hinder their ability to learn about the world outside of each other.
Because of these issues, most good breeders will not sell littermates to a family at the same time. If a breeder is eager or willing to sell you littermates, this should be considered a red flag and you should research this breeder a bit further. While there may be exceptions to the rule, it is generally never a good idea to have two puppies at the same time. You are much better off if you raise one puppy, put in the time and training and then bring a second puppy into the home once the first is a young adult.
