Is it safe to get a second GSD? Will two male GSDs get along?

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!

They should be fine together, of course it is highly recommended to have them both neutered to avoid any aggressive tendencies, you should also introduce the puppy under your supervision only for a long time until you are sure your dog can be trusted.

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!

Yes, they can get along, but I would make sure your male is neutered if he isn't already or you will get puppies. This website will give you tips on introducing them: http://dogtime.com/dog-health/general/712-bringing-home-a-second-dog-aspca

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.

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.

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.
