I would just go with the flow right now. Ride it out, and give it time.
These two shelties will work out everything, and become best friends. It just takes time. And you should give it every chance.
Even Bella will learn to settle with Steve. You can see her trying, when he is seated, and won't be moving toward her. She has to feel comfortable in her own time. (ask Ann about this with Lacey).
As far as the food, I would throw out the canned, use the kibble adding a little baby food chicken with water for flavor, then back off the chicken until she is eating her kibble.
I believe I posted this in one of your other threads, but I can say from experience you have not had her nearly long enough for her (or Laddie) to adjust. As missjennygirl said, when Lacey came home to us it was much like your situation, times 3. We had three other Shelties, and Lacey was very needy and timid and afraid of her shadow. Worse, she was terrified of my husband and would not let him near her. She wouldn't eat for the first month she lived here, except in her crate in the middle of the night when she felt safe.
There were several times that Connie (missjennygirl) and I talked about sending her back. DH and I just couldn't bring ourselves to give up, as frustrating as it was, especially for him. He loves the dogs so and really tried to win her over.
Then a friend who is a behaviorist told me to have DH completely ignore Lacey...not even to look at her. It was hard, but that's what he did. Slowly, ever so slowly, she began to come around. It took more than six months. One day a switch flipped in her little head, and she went to him. We couldn't believe it. Now he is her best friend and goes to him for affection and pats. We often marvel at how different it is from when she came.
She began eating normally after a month or so, again slowly and with some coaxing. As she became more secure and confident with us and her surroundings, the other dogs began to accept her. Now she's a member of the pack and holds her own.
I agree with Connie. Give it time, and be patient. Laddie will adjust. If you feel the play is too rough, don't hesitate to say NO firmly and dial it down. They will figure it out but you have to be the alpha. Bella will realize that you are in charge and not Laddie, and then she will become more confident. Rolling over on her back is a submissive behavior. Bella was clearly low pup on the totem pole in her previous group of dogs. She needs to gain confidence and find her own place in your herd, both human and canine. It will take time but it will come.
Laddie is exhibiting normal behavior regressing and eliminating in the house. He's staking out his territory. He'll get over that too. These things are all adjustment issues. If you can hang on and persevere, in a few months you won't believe she's the same dog and they will be best friends.
F-kap would sleep in my bed, Jody in the play pin by my bed. Eventually things started getting better. They still arn't BEST friends, but it's much better and I don't have to constantly watch them. They play nicely for a while (F-kap's hips bother him, so there's only so much playing he can stand).
We just have to see, I will give it more time, but if it gets worse, one leaves, and I feel it will not be my Bella, what a mess.
