There is a big difference between using a head halter to take the dog for a walk and leaving it on all day. I would never leave any training device on a dog when not in use, much less all day. That goes for a head halter, choke chain, pinch collar or even a harness. Do what you feel comfortable with but each type of tool has it's place and time for use. Just remember that you have a baby puppy and the less force the better. Good luck!
