Wow - never thought I'd have this problem. My pup is 14 weeks old and I can't get a harness on him - at all. He freaks out, runs, and hides under the couch. He's so wiggly, I can't even hold him still. I've introduced the harness to him the past couple of days, used treats, had him smell it, step in it, touch it. I guess it's urgent for me because he's pulling like crazy on his leash and I'm worried it might damage his throat. I'm going to puppy school and we are practicing walking the right way, but I live in an apt. and as soon as he steps into the hall he wants to run down it to see people. So he pulls and pulls - but only in the halls. When on an actual short walk, he's great. I've only ever had one dog before - a Havanese - and never had this issue. My little guy just won't have it. Any suggestions?
