  Is this for a Yorkie?  Why would you need a training collar for a Yorkie, if you are referring to one?  Yorkies should n e v e r wear collars that are attached to a leash.  Check out the sites for collapsed trecheas.  Some Yorkies have that and have never used a collar, but the chances are greater if you do use one.
