On June 3rd Rocky was stated to be 14 weeks old.

Agree with Mick as to training etc. and not using any sort of corrections (what a prong or chain choke collar does do) with such a still young, and untrained pup.

Not sure about Halti (or other similar head halters) in situation you describe where it sounds like dog is running off? Neck of dog can be seriously hurt in such situation. But could be that with treats etc. on leash this would be a way to work on leash walking nicely. Suggest you do a search here for the many discussions we have had pro and con about use of head halters. Term GL or Gentle Leader may bring some of it up too.

I guess I have never faced situation where a pup that young had to be leash walked on sidewalk etc. Have always had some sort of yard if in suburbs or country, or park if in city available to take a pup to. Do you not have these other options?

If you do have a yard of park, then, How about a long line (basically a light rope with a thing on end to connect it to collar or harness) connected to a regular harness or collar for such a young as yet untrained pup. He can get the running and exercise he needs without being able to run off.

If you add a thing called a "snap back" which is like a bungee cord with useful bolt snap attachments, you can further minimize risk of injury. AND keep the exercise area somewhere that is basically safe.
