I hope you don't mean to use the prongs on your puppies, and are just getting the collars now to use when they are older.Originally Posted By: KCandMaceWith my White GSD we did. After the first few times we just had to put it on and it was like a "Hey! We are working now" Kind of thing and he would settle right down and get to business. If it was off he always thought it was time to play.
We just ordered two for our pups but they are not the metal ones. We are going to try these out and see how they work.
