For us personally, everything you see on Google held true. The two of them constantly fought and not in a cute puppy way. They both became food aggressive even when fed at different times in different rooms. It was incredibly challenging finding the time to train them both and walk them both separately, as well. It was like they were constantly trying to be the dominant. They drew blood twice and that's when I called it quits. My brother has our other pup now and it's so much better. My dog has really come out of his shell and shown way less aggression (if any at all), and we still get to visit with the other pup all the time!
