One thing that I know really helps is keeping to a schedule for potty-training, once every 2 hours or so and right after meals take them outside, that way there are minimal accidents. Also, If your puppy has a problem with barking, there’s this tool you can use that is very humane but stops them right away! I forget what it’s called, but basically it’s a little handheld stick that when you push a button, it emits a noise that only dogs can hear and makes them stop whatever bad behavior they are doing right away! It seems like false marketing, but trust me, I’ve used it and it really works!
