When we got our Yorkiepoo Kobe (now 16 weeks), he refused to walk on the leash, or wear his harness, or a sweater without a fight. But we kept working with him a little bit every day and now after about a 6 weeks, he's used to wearing the harness, leash and sweater.
Now he will every now and then reach up to grab the leash, but he enjoys going outside more!! I think it just takes time and patience.
