I've had both...not at the same time though. Raising a boxer pup was very challenging. She was a good dog, but not very bright. These are both 3 years old, so they should already be trained at least.

If it were me, I'd get another BT for simple size considerations. That sounds like an already crowded situation, and a bigger dog could make it worse. Boxers make good house pets despite their size, but personally, I'm of the believe that larger dogs need room to run.
