Since you said that your dog tried to harm her, she's probably just in shock. We had a similar situation with my Roborovski & my cat (not a good combination!). She had escaped and I found her cowering from my cat in a corner of the room. After checking her over and finding no marks, bites scratches etc., we put her back in the cage. She didn't come out for a few hours, and seemed very wary of most things - including her sister - for a couple of weeks afterwards. As long as the hamster has no injuries and seems to be eating a sufficient amount, I wouldn't worry too much about it, as it's a natural reaction with hamsters being common prey animals.
