Ok, I said that just to get your attention, (forgive me!) the truth is our 6 month old collie/new zealand hunter way cross, jumps up at kitchen surfaces and table and our trainer has said that we must just ignore it but to be absolutely sure that he never, ever, ever gets rewarded by finding some tasty morsel to make it worth his while. Needless to say, he has twice been rewarded by slack humans in the household leaving stuff within reach. He is big and can get stuff out of sink and right from the back of the surfaces. I had started to spray him with water when I caught him doing it, but trainer thinks any intervention is unnecessary and undesirable. Thoughts please?
