Is it safe to get another GSD puppy with an unsocialized dog?

I'm so glad you and Bruno have a strong bond! I don't think it's a definite that he and another dog will fight when the puppy grows up. However, I would recommend that you introduce them carefully and slowly, and always monitor their interactions until you are certain that Bruno isn't going to play too rough with the puppy. In addition, I would consider having Bruno neutered, as testosterone increases aggressive tendencies and can certainly contribute to dog-on-dog aggression in some cases.

Most dogs do well with a companion in the home. It will take some initial training on your part to get Bruno and a new puppy used to each other. I would recommend not leaving the new pup alone with the older dog until they are used to each other. It is also important to make sure the older dog still gets plenty of attention and exercise when the new puppy comes along. Good luck!

With any two dogs, it's never possible to completely predict whether or not they will get along - they all have different personalities, just like people. But in my experience, I have not found GSDs to have any more problems with multiple dogs in a household than any other breed - indeed, I have several clients with multiple GSDs who all get along fine. I would recommend getting a female if you can, since male/female pairs are the least likely to have any aggression issues with each other. Best of luck with your new dog, if you decide to get one :)

If she gets along with other dogs then I think an adult dog would be fine. But if she is a threatened by bigger dogs she may do better starting with a puppy. I would allow them to sniff esch other through a barrier like a crate or a baby gate. I would only allow them to be with each other under supervision for awhile until you know that they will be okay together. I would not feed them, give them any bones, or any any toys that she may be territorial over! Most dogs do great! Good luck!

I always think it is better to two dogs than one. I believe they tend to adjust better and do better with training and socializing. As far as whether or not you can keep two unaltered male dogs, absolutely. However, there will definitely be an increased chance for fighting than if they were both neutered. Training and socialization will be of utmost importance at an early age if this is your plan. Hope this helps.

Bruno won't be fully mature physically and emotionally until he is at least 18 months to two years of age. That's because large breed dogs mature slower than the smaller breeds of dogs. But that doesn't mean you can't get a puppy now, and I would recommend having Bruno neutered before getting another dog. Unneutered dogs can and do become very territorial and aggressive when intact dogs enter their home, and that can cause a lot of problems for you to deal with daily. In addition, if you get a female, this can lead to unwanted puppies when she goes into heat. GSDs are a very active breed, and if you have the time and energy to give both dogs all the exercise, attention, and training they need, there is no reason why you can't get another GSD.

If your german shepard is not well behaved or aggressive I would highly recommend getting him under control before bringing a new dog into the situation. If he is aggressive as in growling/biting at people he should see a veterinary behaviorist. If he is just wild/doesn't listen, he should go to a dog trainer (with you) to get under control. Ask your veterinarian for a recommendation for a trainer because not all trainers are equal. Once your dog is under control you can consider adding another dog into the household IF your dog is not aggressive to other dogs. You may consider working with a dog rescue who can find a dog for you that gets along well with other large dogs and will allow you to test the dogs out together. Breed doesn't matter as much as personality of the individual dogs.
