You know, we've had Jazzy for 2.5 yrs and Keoki for 8 mos. They play together okay, but they also fight a good bit – nothing I can't put a stop to, but still.... --- even the behaviorist we went to for Keoki noticed immediately, just based on Jazzy's body language in particulary the one time she saw them together, that "These dogs are NOT friends. They may live together in reasonable peace, she has no affection for him at all."
Sounds like your life w/two B's is like our life w/B's and cats. The cats live on the top floor, the dogs on the bottom. Fortunately for the cats, the family room, where the kids hang out to play games, etc., is on their floor. The living room, where we eat, watch TV as a family, etc. is downstairs. So the cats still get a lot of attention. They do, however, sleep in the beds w/the kids, while the dogs sleep in crates.
Good luck. I wish I had some advice.
