I’ve been through something similar with my puppy, and one thing that really helped was establishing a consistent routine for potty breaks and feeding times. Puppies respond so well to predictability, and it made accidents much less frequent over time. I also found that positive reinforcement, lots of praise, and small treats when he did something right were way more effective than punishment. If you’re looking for extra guidance, I found a local program for puppy training Long Island really useful. It takes patience, but sticking to a routine really made a difference for us.
