Hi everyone. I have 8 months old GSD and 4 months miniature pinscher. I'm thinking about to get a female GS puppy. Some people say tell me wait for 2 years for my GS puppy become mature and then having another one. What do u all think about this? When is the best time for me to have another puppy? If I get one one, does it cause misbonding between me and my dogs? Because currently 2 of my dogs are still puppy. What do u think? Any input will be appreciated. Thanks so much..
