Steve if you post your puppy questions in the puppy section you might get more responses and advice.
If your puppy has never worn a collar before it might be bothering her but she will get used to it. It is kind of like you putting on a new pair of shoes, she might feel different until you get used to them.
If your puppy continues to whine, show lack of interest or not eat, she may not feel good which would have nothing to do with er collar.
