When she gets up to go walk the dogs, get up and go with her. Do not mention it ahead of time. Don't try to get her to work "us time" into the schedule. Don't discuss anything like this -- just act. Don't give her the opportunity to say your idea is a bad idea. Discussions only open the door for her to shove all her reasons in the way. Her reasons aren't reasons, just excuses, so no point in encouraging them.

Wanting to do the right thing and being nice are fine. Avoiding conflict when conflict is necessary is not a good thing. Rescuing BB is not a good thing-- because for one thing you don't really rescue her, do you? When you try to rescue her, she just pulls you down into the pit with her.
