Good luck in your search for a new house Kandi. When you say Dane has been aggressive, is it real aggression or the "stop that dumb puppy", I see on Hera here, that when Galahad is being too much, she tells him to cool it, she is real good with him has so much patience, he is hanging in her lips, tail, ears and steal every toy she gets. But sometimes she just wants to have som alone time, and then she can tell him to back off, if he is bothering her too much, and that is a good thing, he needs to be put in line, and know that he can not get away with just about anything with other dogs. So if that is what Dane is doing he is just being a good big brother, mind you if he is being too rough and you can tell that he is getting aggressive for real, not just telling Jasmine off, you probably want to monitor them quite closely.
Dane not lisening, can be a reaction to the change in the home with Jasmine there. But it could also be a reaction to how things are now, they are soooo good at feeling if the situation is not "right" if you and your husband are worried, unhappy and frustrated over the situation with the landlord you may send out those signals and they feels it, and get just like kids when they sense something is wrong, go all bad behaved on you. Jasmine has not been with you for very long, so she may still be settling in, when you train her do you have Dane there too, or do you get her somewhere, where she can be alone, if not that may be a good idea until she feels a little more sure of herself.
And do I have the greatest respect for you or what........ three kids all under 3, ouch....... I have mine spread out and still think they are way too many sometimes lol....
