First of all I hope you're all enjoying the holidays. I wish you and your families all the best.

I read on a post that yorkies should wear harnesses not collars. And especially since next week I'll be taking Tiko to have his trachea x-rayed since he seems to gasp once in a while. He's been wearing a collar since I first got him, he's now 5 months. I've had a lot of trouble getting him to walk on the leash, he starts biting it, he tries to bite the collar whenever I'm putting it on or taking if off. I just enrolled him in a training class, and he's required to wear a training collar, which can really tighten around his neck. He's only been to class once so far and he nearly choked and was gasping. I've since been using it at home for training but very carefully. What do you suggest? If you've taken your yorkies to training classes what have you used. Of if you've trained them yourselves what have you used. Do your yorkies go crazy biting their leashes. Any tips?
