That sounds like he might be going through a “fear period.” It happens even if the puppy has been well bred, well socialized, well trained. It’s just part of their development. Take note of his triggers and continue your training. Never coddle the dog. He should grow out of it eventually.

Not only does your puppy have a short attention span because she’s a young pup, she will sometimes stutter when performing behaviors because perfect compliance takes a while. When my puppy was that small I usually started each training sessions with basic luring before I asked her to do the behavior without the lure, specially when there were distractions around. This served as a reminder on how to do the behavior.

Basically, if your puppy is failing so much, it’s probably because she doesn’t fully understand what you’re asking and there are too many distractions. No need for corrections at this stage.
