Like Vanessa said, I think those of us that have added a baby girl b to the pack can relate to how much of a PITA they can be at times (understatement). :D:D Also, what Vanessa said about having the dogs meet each other outdoors is always prudent…
I've never had a problem with my own little "demon seed", Liyah :D:D creating problems with other dogs in others homes...but my friends dogs are super tolerant of her puppy behavior...and in general Liyah LOVES other dogs, so she is all about play with them no matter what the situation has been. Luckily my friends dogs enjoy the play.
For me, at home is where the challenge is. Now that Liyah is getting older (5 months tomorrow), my 2 adult b's are much less accepting of her puppy antics and so the noise is getting louder. One thing I've been doing is that if I can see that Liyah is starting trouble (for the 10th time), I'll take her outside, separate from the other dogs and play chase or ball with her on my own or something with her that gets her flying around the yard, burns up some energy, gets her tired and takes her edge off...probably 10 - 15 minutes of outdoor "games"...good hard physical exercise. Then when I bring her back in, usually she is much more relaxed/tired and will stop picking on the adults. She doesn't pick fights, she just wants to play, but Ruby and Brando (especially Brando) get fed up with being chewed on all the time.
I'm just wondering if you could really get her tired before you bring her to your friend's house and maybe the adult dogs would be more accepting of her antics.
Also, has she been to other houses with dogs, and if so, how has that gone...is the problem just with these 2 dogs?
