I am guessing you got Finnick on 3/2? So she is what 14 weeks old? Or, was that his birthdate?
I think before we consider what is the best method to reprimand a puppy, we need to know how old it is. Reprimanding a 6 week old pup, or a 14 week old pup is very different, as is a 14 week old pup to a 6 or 12 months old.
With more information, we can give you better advice.
