It sounds like Caro is the more dominant of the two. It often happens that the smaller one can be the more dominant.
Mostly I've found that litter sisters get on fine & can be inseparable, my two younger Skyes are like that. Where you see one the other is never more than a few feet away. I have a pair of old Cairns the same, they sleep together & always used to foster each other's puppies. Two of my other oldies are brother & sister. He pines for his sister if they're ever separated.
But it doesn't always happen like that. You can sometimes get a real problem. I kept a pair of litter sisters, and later two brothers, who were fine as puppies. But as they reached adolescence, that's often when trouble starts around 8 months to a year, they began to fight. Not just squabbles, really serious fighting. The two brothers, both of whom were successful show dogs, I had to keep separated for the rest of their lives. Just seeing each other used to set them off rowing.
The two bitches were even worse, they often are far worse than dogs if they take against each other, & would have inflicted serious injury on each other if they could. Breaking up one of their fights landed me in A&E with the top of my thumb missing!
I had to rehome one of them, there was no way I could keep them both. The one I kept was perfectly fine with all the others afterwards, as was the one I rehomed. She never showed a hint of aggression with her new owners, it was just each other that they couldn't abide once they grew up.
