Does your dog know any odd words/commands? Josie knows a few..
look - she'll start smelling the floor where I point (looking for food)
food/supper/breakfast/eat/hungry - knows shes getting fed
cottage/car - going for a walk
wana go out for a pee? - seems to know it means go outside
Theres probably more I cant think of...she knows other stuff but those are the more odd ones
