Ok, here we go. I have a 6 month old Shih Tzu named Jackson. The thing with Jax is that he does good during the day and evening with going potty. He goes out in the morning, noon and finally at night with my other dog, who is a few years older that Jax. The problem Im having with Jax, is him going potty in the house between the hours of 2-5am. I just need him to get past this stage, and he'll be 100% PERFECT!! I hope you all can provide me with some great insight. Thanks in advance.
