|   Loki and his bells 
  Here's Loki and his bells that I made are behind him.  I put 4 sets on there so it's loud enough to hear all over the house.  We just asked him to ring them (he either swats at them or nudges them) and then said "OUTSIDE!" and went right outside.  I would put his leash on him first and then do this.  When he would sit near the door or scratch, I would ask him to ring the bells first and then we would go out right away.  After a few days of directing him to the bells he would ring them on his own.  Now he's been doing it about a year and it's second nature to him.  |
