Oh, here is a tip, from when I went to a prof. dog trainer. Use one of those long handled wooden spoons,(I got a set from the dollar store) and put some peanut butter, cheese spray from a can, or some other sticky treat on the spoon part.A tiny amount!!! Then hold it so that the treat part is hanging just in front of him as you try to lead him with your leash. Great way to teach heal also
Good luck
