I just read this whole thread - so it doesn't look like you yet know if she's pregnant, right?
In any case, my heart goes out to you - adjustments can be tough. I would just say that it helps to try and remember that she's probably scared, nervous, tired, insecure - and she's in an
entirely new environment. She's also picking up on your feelings as well (whatever they may be at any given time). Being older than little wild man Franklin (one of my fave YT names, btw!
), it is natural for her to need to "pull back" a little - they will likely establish a relationship where it will be up to HER when and if they play (and this will loosen up over time) - and that's normal.
Also, outside of your relationships with them (and within the pack) they are, right now, establishing their ground rules and heirarchy between each other - and if you interfere with it, it will end up being very confusing for them in the long run. The best thing you can do is remember that YOU are alpha - and then watch them to see eventually who is next in line, and respect what they've worked out. And they'll be SO much more at ease if you allow this "order" to work. They also have such different energy levels right now, so it's tough.
I don't think that she doesn't "like" stinkin' little Franklin - she's just trying to let him know a few things. Just love them both up, have play sessions with them together - and allow
her to tell Franklin "no", if she needs to. And, just love her to death and bring her into the fold as much as possible so that any anxieties dispel as well. Wylie had to adjust to Marcel too - and he was SO insecure and needy when we brought Marcel (puppy) into the house - and now, total buds. But, Wylie is the boss - he's older, more uptight, and has a need to be the boss.
A good book I'd recommed is The Loved Dog by Tamar Gellar - GREAT. Sorry for writing so much!
Geesh!
