Dog Discipline

What could these two pictures possibly have in common?  Buzzy is adorable, but he does have a little flaw.   He feels compelled to scratch soft fabrics.  My new bathroom rug is quickly balding.  I have to groom it every time he gets in there.  He gives carefull attention to several other rugs, but this one must be substandard.  I do tell him,”No!”  He is pretty forgiving, just gives me a hurt look and walks away.  I’ve thought of flapping him with a hand towel, but that seems a little extreme for a ten-year-old gentleman who’s never endured a flap.  I guess I need to buy a better rug or keep the door closed.
