I believe if you feel a pinch is your only or last resort on a five month old at this time, then somewhere along the line your puppy is/was getting mixed signals from you. A simple buckle collor should be doing the trick right now. I think you should find yourself a good trainer who offers puppy classes and enroll asap. Corrections are not being offered clearly....clearly! I believe you and your puppy would benifit greatly now and for your futures from a professional.
