My puppy, Jessie (10 month old), was never afraid of hard wood floors until 2 weeks ago. I guess she slipped on the floor and now she won't go on it. My house is basically all hard wood except a few rugs. She'll go on the hardwood to get to rug to rug but that's it. if she's really hungry she'll have her back paws right near the rug and stretch for her food and then she'll back up again to the rug. How can I get her over her fear? is there some kind of clicker training I could do? and uhm... where would I get the clicker?
