My new puppy, Duke (13 weeks old, lab mix) has no problem with his collar. He does however have a problem with a leash. As soon as the leash goes on, he freezes. He will stand there and just occasionally shiver. I want to get him in obedience classes but know I can't do this unless he's able to go on a leash. I am currently just putting a leash on him and letting him walk around with it. He seems to be getting used to it but when he goes outside, he still freezes. Any help would be appreciated.
