My dog is a year and a half old Australian cattle dog mix. I adopted him a little while ago from a shelter, and at first things were fine. But now he has started to pee when I put a leash on him to take him out, at first I thought I was waiting to long to take him and he couldn't wait. But he does it every time, I scold him when he does, then take him outside, and if he goes outside I praise him. But it's only getting worse, and at this point sometimes he won't go until I bring him back in! Please help if you can!
