There’s a difference between white background noise and noise of other people talking in a restaurant - that’s what I really struggle with, I think because my brain wants to interpret all of it and has trouble focusing on the person I’m listening to

One point of correction - good pinch collars will have blunt prongs - not pointed prongs. Putting the pinch collars on our 45 lb. dogs + a little bit of training has been magic. You try to walk them on their flat collars and it’s a nightmare, put the pinch collars on and they’re angels.
