Chato just turned 5 months. I took him home with me for the holidays. I think it was a big mistake. Up until this point he was a 3 out of 4 dog. Three times outside for everyone inside. Well while at my parents he stayed out side with thier dogs and upon returning I realized he was now a 3:1 dog. Three inside for one outside. Am I going to have to restart his training everytime I take him to my parents or just until he is 100% house trained?
