My 10 wk old puppy REFUSES to go outside 8 out of 10 times. It doesn't matter how many times we go out or how long we stay out he's gonna hold it until we come in. I always clean up right away and never scold or punish. When he does go outside I give lots of praise and treats. I have caught him just as he was squating to poo and rushed him outside. He just held it and begged to come in for so long that I gave in cause I was afraid he'd get constipated. He absolutely does not want to go outside. That's just one example but I could go on and on. Please help me!
