Help please . Everything I'm reading is about dogs PULLING the leash. I have the opposite problem. My 20week old pup puts the breaks on and refuses to walk. She's used to her collar and leash (just not with me holding it trying to walk her). We have had the leash on her and let her roam the house freely (with supervision I course), and she does just fine. But the minute I pick it up and she's aware I'm "walking her", she throws the breaks on. Any tips?
