PSA: Shifting a rug around fixed my puppy's potty training issues
My puppy kept having accidents in the same corner of the living room, no matter how often I took him out. I was about to give up and just accept a smelly house. Then, during a big clean, I moved a large area rug to cover that exact spot. Suddenly, he stopped going there and started using the patio door like he was supposed to. I think the change in texture under his paws messed with his usual routine. Now, I keep the rug there as a permanent reminder for him. It cost me nothing and saved my floors. Maybe try altering the environment before you lose your mind over training.
