Does anyone on here use clicker training?  If you do, what treats do you use?  I'm looking for something sugar free (or low sugar) that is small (so it doesn't take forever to chew), but that's easy to give one treat at a time.  I've tried pellets, but I drop too many.  I don't like to be wasteful.  Right now I'm using horse treats, but they are a little big and have too much sugar in them.  I've tried miniature hay cubes but it takes him forever to chew them.  Any ideas?
